Geophysical Survey Systems, Inc. SIR® 30 Manual

Chapter 1: Introduction

Thank you for purchasing a SIR® 30 GPR control unit from GSSI. The SIR 30 represents the current state of the art in high-speed, multi-channel GPR data acquisition systems. The SIR 30 has been designed to work with any of GSSI’s current and older line of GPR antennas. The SIR 30 also offers many integration options, so it is easy to integrate GPR to a multi-method data collection vehicle.

Please take a moment to unpack your order and ensure that everything is present. Contact GSSI or your local GSSI representative immediately if you notice anything missing or damaged. A GSSI representative can be reached at (603)-893-1109, 8:30 AM – 5:00 PM US Eastern Time, Monday-Friday. You can also email sales@geophysical.com

GSSI recommends that the User(s) completely review this manual before using your new SIR 30.

Unpacking the Box

Your new SIR 30 comes in a Pelican Model 1650 transit case with custom-cut protective foam. The transit case has been designed to protect your SIR 30 from the elements and from damage. GSSI recommends keeping your SIR 30 in its protective case when not in use.

The basic SIR 30 system comes with:

• SIR 30 controller

• AC Power supply: Power adapter for powering the SIR 30 from and AC outlet.

• SIR 30 User Manual

• Documentation CD: The CD contains an electronic version of this manual as well as all of

GSSI’s other radar systems and antenna manuals.

Geophysical Survey Systems, Inc. SIR® 30 Manual

Key New Features of the SIR 30

Increased Data Acquisition Speed: The SIR 30 can transmit at a maximum Pulse Repetition Frequency (PRF) of 800 KHz. This PRF enables the SIR 30 to collect more than three-quarters of a million samples per second. Unlike other GPR systems, the maximum PRF is not reduced when operating multiple channels simultaneously. This unique capability allows the GPR User to collect more data faster than ever before.

Note: Not all GSSI antennas are capable of operating at the maximum Pulse Repetition Frequency of the SIR 30. Consult your antenna manual\documentation for the appropriate antenna PRF. Setting the SIR 30 PRF higher than the maximum antenna PRF will result in poor data quality.

Data resolution: The SIR 30 incorporates fixed 32-bit sampling. This means that the SIR 30 has superior dynamic range than other systems using 8, 16 or 24 bit sampling. The increased dynamic range will enable the User to recover weaker signals with SIR 30 than other GPR systems.

Data Processing: The SIR 30 system applies filters and gain during data acquisition for display purposes only. All data is stored raw. The acquisition filters and gain are stored with the data file and will be automatically applied in RADAN 7 if so desired.

Chapter 2: User Interface Descriptions

This section will familiarize the User with the various menus of the SIR 30. GSSI recommends that the User read this section carefully to gain an understanding of the menu structure and UI (User Interface).

System Start Screen

Figure 18: HDMI SIR 30 server system start screen.

Figure 19: Laptop system start screen.

After powering up the SIR 30, the system display will present the Start screen as illustrated in Figure 18 above. The User must select the system of linear units; either Metric or English, to be used for the survey. Once the User has selected the system of units, the SIR 30 will present the System Setting Screen.

Note: Once the user has selected a system of linear units for a survey, these units cannot be changed during data collection.

System Settings

After selecting the desired linear units from the SIR 30 start screen, the SIR 30 will display the System Settings menu shown in Figure 20 below. It is here that the User will specify the geometry of the data collection setup i.e. the position and location of the antenna(s) relative to the location of the GPS receiver, the offset distances of the GPR antennas from the GPS receiver, the desired scan density and mark spacing as well as specify the type of antenna(s) connected to the system.

Figure 20: Initial system settings.

DISTANCE CONTROL

These parameters control the horizontal scan density. The horizontal scan density, or Scans per Unit distance is recorded in the units selected by the User from the System Start screen. In Figure 20 (above), the option shown is 12 scans\ft. The horizontal scan density should be set high enough so that the smallest feature of interest is detectable yet not so high that large amounts of extraneous data are collected. The horizontal scan density required for a specific application is dependent on many factors including the electrical properties of the media and the target or structure of interest, the wavelength of the antenna center frequency, the speed at which the data is collected, the depth of the targets, their size, etc.

UNIT/MARK: This setting controls how often the SIR 30 will write a distance mark in the data file and on the data acquisition display. Distance marks provide the User a quick visual indicator of distance travelled The Unit/Mark setting is stored in the radar file header.

MAX UNITS/FILE: This setting controls the total expected size of an individual data file distance units. When you start data collection, the SIR 30 will reserve a block memory sufficient to store the file. This number does not need to be exact. If you leave this setting at the default value of zero (0), the SIR 30 will reserve a memory block equivalent to 5 GB per channel.

The User has been provided with a service utility called Sir30 Calc.exe. It is located on the USB Maintenance Tool, which shipped with your system. This tool allows the User to input any data collection parameters that will affect the File Size, Scan Rate, Scans per Unit, Scans per Second, Samples per Scan, Units, Max Units/File, Distance, Transmit rate of SLOWEST Antenna and Channel Configuration. By changing various parameters, the User can determine the following:

• The maximum scan rate (Scans per Second) possible with a given configuration.

• The maximum speed of data collection (Km/h or M/h) possible with a given configuration.

MN 93-101 Rev E 18

• The output file size (in GB).

• The Maximum Units per file.

• The data improvement factor. This is equal to the number of repeats per sample.

GPS

If you are using a GPS with the SIR 30, select CUSTOM from the GPS Type and enter the location of the GPS receiver antenna wi th resp ect to the GPR antenna connected to Channel 1. If the GPS antenna is mounted to the Channel 1 GPR antenna, both the X and Y values will be zero (0). If the GPS antenna location is behind the Channel 1 antenna location, the X value will be the distance of the GPS behind the GPR antenna, and the number will be negative. The Y value determines how far to the right or left the GPS is relative to the GPR antenna connected to Channel 1. If you are standing behind the antenna, facing in the direction of your survey profile, this number will be positive if the GPS antenna location is to the left of the GPR antenna and negative if the GPS antenna location is to the right of the GPR antenna.

Figure 21: GPS set to CUSTOM, GPS is enabled.

Figure 22: GPS\GPR Antenna position configurations.

The diagram at the top of the System Settings menu provides the User with a quick visual aid for describing the GPR antenna position relative to the GPS antenna location (Figure 22). The GPS offset positions (if any) are saved as the In-line (X) and Cross-Line (Y) offset values in the file header and are used by RADAN 7 to correct the antenna offset positions for processing multi-channel files .

Figure 23: Antenna channel descriptions.

ANTENNA(#)\CHANNEL

The antenna options correspond to the Channel 1-4 inputs on the back of the SIR 30. For each antenna channel, the User can enter the Antenna Type (Center Frequency), the antenna model number, the antenna dipole orientation i.e. the dipole polarity axis orientation relative to your profile direction, the antenna serial number, the transmit rate, the transmit-receive mode and the GPR\GPS antenna distance offset values.

• The antenna serial number is required if you are using a Model 4105NR 2 GHz Horn with noise

reduction technology. The SIR 30 will use the provided serial number to select the correct Custom filter file.

• If you selected an antenna model, the SIR 30 will automatically load the maximum poss ible tr a nsmit

rate (abbreviated Xmit Rate) for that antenna. If you would like to set this manually, you must select CUSTOM from the Antenna Type pull down menu.

Note: In cases where the maximum transmit rate (or PRF) of the antennas is different, the SIR 30 will use the highest transmit rate that is common to all antennas e.g. If two (2) antennas are connected to the SIR 30 and one has a maximum PRF of 100 KHz and the other has a maximum PRF of 330 KHz ,the system will use the 100 KHz PRF rate.

• TX-RX Mode allows the User to set the system for Standard transmit\receive mode, Bi-Static

transmit\receive mode (Transmitting from one channel\antenna to another channel\antenna), or Dual Receiver Mode. (Transmitting from one channel\antenna to another antenna in b-static mode and one channel in Standard transmit rec eiv e mode).

• In-Line (X) and Cross-Line (Y) Offset are the offset distances from the GPS receiver antenna relative

to the GPR antenna connected to Channel 1

• Clicking Accept will cause the data acquisition mode and antenna(s) to initialize and the display the

Data collection Control Screen.

We refer to the left hand column of the Setup Controls as the Main Menu (Red) and the right hand column as the Sub-Menu (Blue). The SIR 30 user interface is structured so that the User moves through the control settings from top to bottom. When you select one of the Main Menu buttons, it will turn solid blue and the options in the Sub-Menu will change.

There are four buttons in the Main Menu:

RADAR CONFIG (page 27) SIGNAL PROCESS (page 41) OUTPUT OPTIONS (page 47) SYSTEM OPTIONS (page 56)

Note: If the User is operating with more than one channel and you wish to change the acquisition parameters of any individual channel, you must activate the specific channel display before making any parameter changes. If the system is operating in multichannel mode and the User makes a parameter change with all channels displayed, the parameter change will be applied to all channels (See Figure 27 below). In this mode, the parameters displayed by the system will be those of Channel 1.
