FCC Notice (for U.S. Customers):

This device complies with part 15 of the FCC Rules:

Operation is subject to the following conditions:

1. This device many not cause harmful interference, and

2. This device must accept any interference received, including interference that may cause
undesired operation
Warning: Changes or modifications to this unit not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
Operation of this device is restricted to law enforcement, fire and rescue officials, scientific
research institutes, commercial mining companies, and construction companies. Operation by
any other party is a violation of 47 U.S.C. § 301 and could subject the operator to serious legal
penalties.

Coordination Requirements.

(a) UWB imaging systems require coordination through the FCC before the equipment may be
used. The operator shall comply with any constraints on equipment usage resulting from this
coordination.

(b) The users of UWB imaging devices shall supply detailed operational areas to the FCC Office
of Engineering and Technology who shall coordinate this information with the Federal
Government through the National Telecommunications and Information Administration. The
information provided by the UWB operator shall include the name, address and other pertinent
contact information of the user, the desired geographical area of operation, and the FCC ID
number and other nomenclature of the UWB device. This material shall be submitted to the
following address:

Frequency Coordination Branch., OET
Federal Communications Commission
445 12th Street, SW
Washington, D.C. 20554
ATTN: UWB Coordination

(d) Users of authorized, coordinated UWB systems may transfer them to other qualified users
and to different locations upon coordination of change of ownership or location to the FCC and
coordination with existing authorized operations.

(e) The NTIA/FCC coordination report shall include any needed constraints that apply to day-to­day operations. Such constraints could specify prohibited areas of operations or areas located
near authorized radio stations for which additional coordination is required before operation of
the UWB equipment. If additional local coordination is required, a local coordination contact
will be provided.

(f) The coordination of routine UWB operations shall not take longer than 15 business days from
the receipt of the coordination request by NTIA. Special temporary operations may be handled
with an expedited turn-around time when circumstances warrant. The operation of UWB
systems in emergency situations involving the safety of life or property may occur without
coordination provided a notification procedure, similar to that contained in CFR47 Section

2.405(a)-(e), is followed by the UWB equipment user.

INTRODUCTION

1.1.

Purpose and the Field of Application.

The georadar is the facilities for subsurface profiling purposed to obtain
continuous profiles of subsurface structure of ground along the survey line.

The principal fields of application are:

mapping of the surface of bed-rock under the layer of mellow deposits;
search of pipes and cables;
glaciology;
archeology and criminal law;
search of cavities in;
mapping of water table in sand deposits;
mapping of bottom and bottom deposits of fresh water reservoirs;
mapping of river paleobeds;
searching of sites of burring of industrial wastes, etc.

1.2.

General Description.

The georadar in operating condition consists of four units: the control unit, the

Notebook computer, the antenna and the battery (see Fig 1). The computer is mounted on the
special platform on top of the control unit. They are connected by the cable with pin
specification shown on
supplied by the battery or a regulated rectifier. The antenna and the control unit are connected

by the antenna cable as it is shown on

150 MHz) they are marked with red and blue labels (see
antennas for transmitting and receiving are shown on Fig. lb where transmitting antenna is
connected to blue connector but receiving antenna to red one. Description of controls and
connectors of Control Unit is on Fig.2. Hereafter are presented brief specifications of different

units of the georadar.

PREPARING OF THE GEORADAR TO OPERATION.

2.1.

Connection of units.

Before to begin to make any connections and switching on please read thoroughly the
instructions below and strictly follow them when connecting units of the georadar. The

connection diagram of units is shown in Fig. 1,

2) Connect the data communication cable to the control unit and to the LAN connector of the
computer as shown in Fig. 1.

3) Connect the power cable to the control unit and to the battery.

4) Assemble the antenna. If a high frequency antenna is applied (1 00, 300, 500, 900 MHz, 1.5

GHz), it is required to attach the handle and to connect the antenna cable to the antenna.

3-m antenna cable should be attached to the handle by plastic clamps or adhesive band as it is

shown in Fig.3. 20-m antenna cable is fixed on antenna by special clamp as it is shown in

Fig.3a. The 100 MHz antenna is combined as shown in Fig. 6. Each 100 MHz antenna has

two 5-pin connectors. Attaching cables to antenna operator may use any of two connectors
because they are connected in parallel. If odometer wheel is needed it is attached to antenna as
shown in Fig. 3b and 6a. Survey wheel is connected to antenna via 3

attach additional dipoles according to Fig.8. The operation combination of the 750 MHz
antenna is shown in Fig. 12. Special cable with color rings on connectors to be connected to
antennas is provided. Assambling antenna you have to coincide color marks on antenna
connectors and cable.

5) Connect the antenna to the control unit. Usually one antenna unit is used for profiling
because it contents both transmitting and receiving antennas. In case when separated antennas
for transmitting and receiving are needed (for example in measurements by Common Depth
Point method) the second antenna is connected to the Control Unit as it is shown in

this case antenna 1 transmits but antenna 2 receives signals.
