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.

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).
Receiving and transmitting antenna unit (BAPP) is designed as a separate part, which is
attached to one end of the folding handle rod. The off-line power supply unit (BP) is to attached to the
second end of the folding handle rod. The control, processing and indication unit (BUOI) is attached in
the middle part of the folding handle rod. Connection between the units is made using connecting
cables.
Two changeable BAPP units: I and II range are used for operation in different frequency
ranges. The length of folding handle rod in a fields status is 0,88 m, in operating position the length is
(regarding on the height of a person) – up to 1,53 m.
The off-line power supply unit (BP 3,8/12) provides the non-stop work of the device for not
less than 4 hours.
