2.3 Arrangements of device operation

The SK operation is based on well-known radiolocation principals. The SK operation is based
on ability of radio waves to be reflected from sections of environment boundaries with a different
permittivity.

Short signal pulses are applied for subsurface radiolocation.

In order to form such pulses the excitation of the wideband transmitting antenna caused by the
voltage swing is used. The direct processing of pulses of such small duration (hundreds picoseconds) is
rather complex. So the stroboscope transformation method is used.

The control, processing and indication unit (BUOI) is to form and to transfer the instructions to
the receiving unit of transmitting antenna unit (BAPP). Receiving unit is to form all the necessary
signals of control for switching on the transmitter. The transmitting unit is to form the signals to the
tested environment (cargo). The reflected signals are received by the receiving antenna unit BAPP,
processed, and transferred to the BUOI.

The control, processing and indication unit is to form two-dimensional image of received
signals and then are to display them on the indicator (screen) in the real time.

The special cable connection on BUOI, cable connect BUOI and computer by interface
Ethernet is stipulated in the device for connecting with the external computer, and for forming three
dimensional image.

2.4 Marking and sealing

The location of sealing wardrobe trunk, packing, BAPP I, BAPP II, BUOI and BP, are
represented in the Appendix 1.

The seal of a wardrobe trunk is located on a long side part of wardrobe trunk, in the upper right
corner.

2.5 Description and operation of the device component

2.5.1 The general

The main components of the device SK is the control, processing and indication unit (BUOI),
receiving and transmitting antenna unit (BAPP) I and II range, and off-line power supply unit (BP).

2.5.2 Operation device of component parts

Receiving and transmitting antenna unit (BAPP)

Receiving and transmitting antenna unit functionally consists of receiving, transmitting units
and receiving and transmitting antenna unit with volumetric damping resonator.

Receiving unit

The receiving unit functionally consists of receiving antenna unit, the scan stroboscopic device,
selection and storage device (SD) and the control unit.

Reflecting from the inhomogeneity in the tested environment the signals are coming from input
receiving antenna unit to output SD, where they are stored at the time of processing. The signals are
coming from SD to the analog digital converter (ADC). The microprocessor receives the transferred
digital signal. The control unit is to realize the preliminary processing of the received data and to
transfer the data to the BUOI.

The signals for start of the transmitter are to form in the control unit and are to transfer to the
transmitting unit.

The scan stroboscopic device is to form the pulses for the SD operation. The selection and
storage unit is to remember the signal by control pulse and is to store it more than 1 micro second. It is
enough time for ADC to transfer the processed analog signal to a digital code. BAPP II is to operate in
the range, where the frequency ranges ADC are to allow the transformation of analog signals into the
digital code without using SD. So for the range of BAPP I the signals from input of receiving antenna
unit are coming to output of ADC.

The sensitivity of the receiving device is not worse than 300 microvolt.

Transmitting unit

The transmitting unit functionally consists of transmitting antenna unit, pulse shaper and high
voltage-power supply unit. The pulse shape at receipt of the starting pulse are to form the (короткий
перепад high voltage) which is to activate the transmitting antenna. The high voltage power supply
unit is designed to transform the voltage of 12V into power which is necessary for operation the pulse
shaper. (duration of a pulse of 1,5-2,2 nanoseconds with fronts up to 0,2-0,3 nanoseconds and
frequency of following 200 KHz.)

The control, processing and indication unit (BUOI)

The control, processing and indication unit is based on the digital signal processor and
functionally consists of all climatic liquid crystal indicator, the control device and the keyboard. All
operations are realized using the buttons located on the front panel. Using the buttons the operator is to
choose the required points or parameters in menu which are displayed on the indicator and is to change
them according with the required task.

According with the choice of the mode and parameters, the control device is designed on the
signal processor, forms instructions and transfers them to the antenna unit (BAPP) using interface RS-

485.

The accepted data are processed and displayed on the screen.

BUOI has the high definition (640x480 points) liquid crystal color display.

BUOI allows to keep the received data in the memory 1Gb (this size of memory is sufficient
for storage approximately 240000 paths), that at the step of scanning 5 cm is about 12000 m of a
continuous profile

7

The data from BUOI can be copied on a personal computer on interface Ethernet. The
transferring order is described in the User’s manual.

The further data processing can be made on a personal computer using Geascan32 software
(see. The User s guide program Geoscan32).

Autonomous power supply unit (BP)

The autonomous power supply unit (BP) consists of ten Ni-Mh accumulators and the
accumulator indicator of the category, which is control and indicate of the accumulator battery. BP

• One should avoid (exclude) heavy blows and mechanical damages in running or transporting

the device.

• The device does not distribute electromagnetic interference (noise) higher than a permissible

noise level.(See Sanitary Certification).

7. Technical maintenance.

7.1 General instructions.

1. During technical maintenance some preventive maintenance is performed to maintain the proper

condition of the device and to provide its normal operation within the service life (8 years).

2. Recommended frequency and types of technical maintenance:

3. External examination – before each running – no damages incompatible with the operation ­isolation damages, cracks and so on may not be available on the case of the device and connecting
cables;

4. External cleaning – once in three months – decontamination of the device and split connectors
surface;

5. Battery charging PU 3,8/12 – not less than one time in 3 months-including power supply units
included in tools, parts and accessories ZIP-0, working as required.

7.2 Maintenance procedure

During the external examination of the device you should test the fastening BUOI, BP and
BAPP to a folding handle rod, paint–and-lacquer coating condition, lack of chips and cracks on the
parts made of glass-fiber material and plastic, as well as on painted parts.

Battery charging PU 3,8/12 is to be performed at reduced voltage 10.5 V, but not less than once
in 3 months ( including Power Unit(PU) from the accessories ZIP-0).
