Glossary

Azimuth Calculated distance of the back scattered electromagnetic signal from a point

of the target area. It is the projection of the position of the point along the

system’s linear positioner longitudinal direction.

Back scattering Signal reflected by an object hit by a radar impulse.

Displacement/deformation

maps Large scale and detailed extended areal graphical representations of the

movements and/or displacements of the target.

Frequency The number of times in which a periodical phenomenon happens in the unit

of time.

Interferogram Complex image resulting from the complex conjugated product of two radar

images. Represented in phase, provide information related to the

movements happened during the time interval between two acquisitions.

JRC Joint Research Centre. European Commission research centre.

Line of sight Line or direction joining two points. It joins the point in which is located the

system to a specific point under observation located in the target area.

LiSA Linear Synthetic Aperture radar. The system is able to measure the behavior

and the damage of structures, such as ground displacement typical of

landslide activity. Such a system uses a ground based interferometric sensor

(GBInSAR) based on the technique of synthetic radar aperture, completed

and integrated by specific software packages, developed for this purpose, to

purchase, process and analyze data collected from the sensor.

LiSALab (technology) Derivative technology developed by Ellegi srl on the basis of the original

LiSA and of the GBInSAR LiSA sensor. This technology belongs exclusively

to Ellegi srl.

Microwaves Electromagnetic waves with a wave length between 25mm and 600mm.

Power or Phase images Each pixels of a complex image representing a part (or cell) of the region in

which the raw data are focalized. It can be associated to information related

to the reflected signals from everything contained in the cell; therefore there

are available two ways to represent the same image, in power and in phase.

The first one provide an indication on the intensity level of the back scattered

signals, the second one on its phase.

Radiometric amplitude Intensity level of irradiated energy.

Range Distance calculated by means of the signal “time of flight” and assuming that

the electromagnetic waves have a speed equal to the light ( 3x108 m/s). It

gives the distance of a point of the target area perpendicular to the system’s

linear positioner longitudinal direction.

SAR Synthetic Aperture Radar. Radar antenna whose dimension is simulated to

be bigger than the real one, sampling the antenna signals when it is in

movement. This technique is useful to increase spatial resolution.

Signal to noise ratio Shortened in 'S/N ratio'. It is the ratio between useful signal measured and

the present background noise signal.

Scan frequency Coherent emission and receiving of a frequency band in discrete packets.

Scatterometer Scatterometer is a radar able to measure the capability of objects to reflect

the electromagnetic energy that hits them.

Spatial resolution In radar technology, it is the dimension of a measuring cell (pixel). Two

User’s guide for the LISAMOBILE setting parameters software

The LEDA © is the program that manages the data acquisition performed by the GBInSAR LISAMOBILE

© system.

In the upper left portion of its interface, in the “Check Instr” box, the LEDA © performs a control of the

status of the main components of the GBInSAR LISAMOBILE © system. If a device is in a “NOK” (Not

OK) status in the “Action” menu the command “Recheck Instr” will perform again the instruments check,

the “Go on” command will continue the process and the “Quit & SD” command will quit the application

and shut down the machine. When the green indicator is switched on the correspondent component is

working properly. If all the devices work correctly a green notification (“All instruments OK”) will appear in

the lower part of the check instr box Figure 2). The devices that are checked are:

• the display;

• the GPS receiver;

• the temperature controller;

• the linear positioner;

• the GSM modem

• the UPS;

• the radio frequency components.

The system display emulator and the command menu box are in the central right part of the LEDA ©

interface (Figure 6). In the command menu under the display emulator are displayed the command

options, the custom parameters currently set and the actual position inside the command menu

(highlighted with a light blue color).

The display emulator reproduces the command display found on the power base and is managed with the

same logic: the menu has different “layers” and the “up” and “down” commands allow to move inside a

layer, while the “left” and “right” commands allow to move in the lower or in the upper layers.

The “Enter” command allows changing the value of the highlighted feature, its value can be changed with

the “up”, “down”, “left” and “right” commands and set to the new value using again the “Enter” command.

The “F1” button is associated to the “esc” function that is “escape without saving parameters.

The “F2” button is a dummy for future use. In the following pictures (Figure 7, Figure 8 and Figure 9) are

presented the main layers of the control menu with a brief explication of the various sub menu layers.

Note: depending on the operating state of the system some features of the command menu might be

hidden.For all the submenus in the “Value” field is shown the value currently set, and in the “Min” and

“Max” field are shown the minimum and maximum values that can be selected.

The “RF par” submenu (Figure 7) allows setting all the “radio frequency” parameters of the system, that

are the start and the stop frequencies (expressed in MHz), the number of frequencies used inside the

selected band, the emitted power (expressed in dBm), the IF bandwidth, the presence of the average

option and the average factor. For further information on the choice of the system parameters please

refer to “Appendix A”. The “Rail par” submenu (Figure 7) allows setting the linear position parameters that

are the start and the stop position of the synthetic aperture, the number of steps performed inside the

aperture, the moving speed of the carriage during the acquisition and the moving speed of the carriage

when returning to the start position.

Figure 8: the “Proc par” and the “Meas Mode” submenus of the LEDA © interface command menu.

The “Proc par” submenu (Figure 8) allows setting the dimensions of the images that will be produced by

the system (if the “processing” option is activated in the “Meas Mode” submenu) that are the image size

(in pixels) and the image minimum and maximum range values. The produced images will have the same

sizes in both the range and azimuth directions and the azimuth dimensions are symmetric.

The “Meas Mode” submenu (Figure 8) allows enabling and disabling the “Stop&GO” mode, the

“Processing” option and the “Join Work” option. These functions are enabled if the “Y” value is set,

otherwise are disabled if the “N” value is set.

If the “Stop&GO” mode is disabled the system will acquire images in the “Continuous” mode, that is much

faster because the system will perform the acquisitions without stopping at each step. The “Processing”

mode enables the images processing, if is disabled only the raw data will be acquired and stored. The

“Join Work” option stores the acquired data in the same work, even if the acquisitions are aborted or the

system is switched off. If this option is disabled the system will create a new work at every restart.

The “Temp control” submenu (Figure 9) allows setting the parameters of the two measuring head fans.

These parameters are the Target temperature, the functioning mode (always “off”, always “on” or

“automatic”) and the low speed and high speed voltages.

Using the “limited power” modality the user is forced by the software to use only values of the above

parameters that are respectful of the ETSI, FCC and IC normatives according the market in which the

system is used.

• For European market according the antennas’ gain the LiSamobile subsystem regulates the

5 dBm 14 dBm 1 dBm

values of the power output to be always below the 26dBm of EIRP.

• For Canada the EIRP is limited to 24.7dBm average.

• In USA the max EIRP is related to the extension of the frequencies, according the FCC par 90 the

EIRP is calculated accordingly. The system limits the maximum “Emitted power at the antenna
input” in order to respect the calculated EIRP given the extension of the frequency.

The system start always in the “limited power modality” and the user can regulates the EIRP according

the antennas gain its currently using.

The changes are made using the “Manage Antennas” menu.

When the “Manage Antennas” button is pushed on the “Main LiSAmobile" control bar the Antennas

Manager Window appears on the user’s screen (Figure 22).

This module allow the user to select the specific antenna models are mounted and used on the system

and to consequently set the system power output in order to fulfill the emission thresholds regulations. It

also allow to import new antennas characteristics and to therefore create an “antennas database” on the

LiSAmobile system that could be then used in order to select the better antennas for each monitoring

campaign respectful of the varius normatives.

The Antennas database is displayed in the upper left list where a checkmark indicates the antennas in

use. For each entry of this list are displayed the amplitudes expressed in degrees of the Horizontal and

APPENDIX A - Technical information and recommendations

Spatial Resolution graphs and parameters setting depending on the

distance from the monitored target

The LISAMOBILE © system produces images having a spatial resolution (resolutions in the range and in

the azimuth directions) that varies depending on the selected measuring parameters and on the distance

of the observed target. Also the maximum range (distance reachable) is linked to the selected

parameters.

In the following graphs are presented the LISAMOBILE system’s theoretical range and azimuth resolution

graphs (Figure 23 and Figure 24) and the LISAMOBILE system maximum range graph (Figure 25).

The theoretical range resolution varies only depending on the used bandwidth. The biggest is the used

bandwidth the better will be the range resolution.

The theoretical azimuth resolution at a fixed central frequency (in this case is 17.2 GHz) depends on the

synthetic aperture length and on the distance from the system. The longest is the synthetic aperture and

the closest is the target, the better will be the obtained azimuth resolution.

The maximum range depends on the used bandwidth and on the number of frequency points. The

highest is the number of frequency points and the smallest is the used bandwidth, the greater will be the

obtainable maximum range.

Therefore, as shown on the graphs of Figure 24 and Figure 25, for normal applications it can be stated

that the LISAMOBILE optimal range is up to 3 km, between 3 km and 4.2 km the quality of the results

could be highly affected by the local conditions, and over 4.25 km the feasibility of the measurements can

not be guaranteed without a detailed inspection on the particular situation.

Having more frequency points will increase the time required for the acquisition of each single radar

image, and decreasing the bandwidth will decrease as well the range resolution of the image. Therefore

the user should set the measuring parameters taking into account the trade off that exists between having

high performances in terms of range resolution and having high performances in terms of maximum

range.

Also the time required for the acquisition of a single radar image could be important, for example in the

monitoring of fast displacements, and therefore the trade off between smaller acquisition times and high

performances in terms of maximum range can become crucial.

IF value setting

The value of the IF parameter affects the speed of the GBInSAR LISAMOBILE © system’s

measurements: the higher is the IF value the smaller will be the time required for a single measure, that in

some applications might result in decreasing the impact of the atmospheric effects on a single image.

On the other hand, higher IF values result in lower levels of the images signal-to-noise ratio, and

therefore lower performances in terms of precision and accuracy of the measurements.

The measurements speed should be set depending on the observed phenomenon features, on the

scenario’s characteristics and on the trade off between fast or precise (and accurate) measurements.

A good compromise is found in the default value of the IF parameter, which is normally set to 5.000.

The LEDA software’s system display emulator (Figure 7) allows the IF parameter value to be set

between 1.000 and 40.000, but it is recommended to change it only if neceaasry. A good solution could

be to firstly change it to a value of 10.000 and perform some measurements to appreciate if changing the

IF value is effective in improving the measurements quality concerning the atmospheric effects impact,

and to further increase it using the same procedure to a maximum 15.000.

Anyway it is always recommended to ask Ellegi technical support and recommendations before setting

the IF parameter to a value that is different to its default one of 5.000.

Example: a procedure for the system’s parameters setting

The optimal setting of the system’s parameters depends on the observed scenario characteristics and on

the desired output features.

The following procedure should help the user in the choice of the system’s parameters:

1. Chose the desired range resolution and consequently select the needed bandwidth according to

the graph of Figure 23;

2. Knowing the maximum distance of the target area to be measured, select the synthetic aperture

length needed to achieve the desired azimuthal resolution, according to the graph of Figure 24. It

is recommended to select the system parameters in order to have similar or equal range and

azimuthal resolution dimentions, extremely stretched resolution cells might produce poor quality

results;

3. Knowing the maximum distance of the target area to be measured and the bandwidth selected in

the first step of this procedure, select the number of frequency points according to the graph of

Figure 25. the maximum range indicated in the graph must be grater than the maximum distance

of the target area;

4. Perform a measure to decide weather or not the time required for the acquisition of a single

measure and the impact of the atmospheric effects suits the monitoring requirements;

5. If the monitoring requirements are not satisfied, an increase the IF value, a decrease of the

number of frequency points and/or a decrease of the synthetic aperture’s length will decrease the

time required for a single acquisition.

Antennas types and emission diagrams

The GBInSAR LISAMOBILE © system can be used with different horn antennas. Different antennas have

different emission diagrams that means wider or narrower visible sceneries, therefore depending on the

monitored scenario one kind of antenna might be more suitable than another.

Because of the peculiar characteristics of each monitoring scenario, the choice of the optimal antenna is

an issue that often requires on field testing.

In the following picture (Figure 26) are presented two emission diagrams for the SGHA-15 and the

SGHA-10 antennas. From these emission diagrams it can be observed that the SGHA-15 has a -3

dB emission beam width of approximately 30°, while the SGHA-10 has a -3 dB emission beam

width of approximately 60°. The area illuminated by the emitted signal is normally wider than the -

3 dB emission beam. The -3 dB beam width is generally used as a safety value.

Precautions for the system switching off

To definitively switch off the LISAMOBILE system at the end of a measuring session (e.g. after a

periodical check campaign or before a maintenance intervention) execute the “Quit” command, then

execute the “Load default parameters” command and finally execute the “shut down” command.

Turn off the LP and MW switches and afterwards the power base main power

switch ONLY after having verified that the display on the power base has

completely switched off.
