1. INTRODUCTION
1.1. Purpose and the Field of Application.
The georadar "Zond-12e" 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 "Zond-12e" 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 Fig.14. The control unit is operated by direct current of voltage12 V
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 Fig.1. If antenna has two connectors (antenna 38-75150 MHz) they are marked with red and blue labels (see Fig.la). Using of two separated
antennas for transmitting and receiving are shown on Fig. l b 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.
Computer. There can be applied in composition of the georadar "Zond-12e" any IBMcompatible Notebook computer operating in Windows 98 1 2000 1 Me 1 XP, equipped with
Ethernet card 10/100BaseT. Information exchange between the computer and the control unit
is performed according to TCPIIP protocol as between two peer network elements. The
computer performs the following functions: control of operational modes of the georadar,
data acquisition, processing and displaying.
Battery. Any power supply providing direct current voltage from 10,5 to 13 V at current up
to 0.8 A. Upon delivery the georadar is supplied with the sealed lead battery with voltage 12
V of capacity 7 Ah, the power cord, and the automatic charger.
Control unit. The circuit diagram of the control unit is shown in Fig.2. Brief description of
controls of the control unit is presented on page 9. Packaging of the unit is shown in Fig.13.
Antenna. Antennas of three types are applied in the georadar "Zond-12e". High frequency
shielded antennas 100, 300, 500, 900 MHz, 1.5 GHz and unshielded 2 GHz antenna are
similar and differ only in dimensions. Theese antennas are intended for operating mostly in
contact with the groung. The low frequency antenna 38-75-150 MHz is of the dipole type
with replaced dipoles for operation at frequencies 150, 75 and 38 MHz. That antenna may be
used in isolation from the ground at distance 0.15 - 0.4 m as well as in contact. Shielded aircoupled 750 MHz antenna operates only in isolation from the ground at distance 0.2-0.3 m.
2. 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, 1a and 1b.
Warning! Before connection of any cable to the Control Unit make sure that it is turned
OFF. It is strongly prohibited to connect or disconnect any cables to the Control Unit or
antenna while the Control Unit is powered.
1) Place an IBM-compatible Notebook computer to the special platform located on top of the
control unit (Fig. 2a). The platform can be turned and fixed in two extreme positions.
Before installation of the computer remove fixing brackets made of stainless sheet steel.
Applying screwdriver unscrew for 1 turn screws fixing movable strips 2. They are free now
and may be stand at distance equal to computer length
If it is necessary to adjust the platform to the computer width unscrew in full screws fixing
movable strips 2 and take away movable strips. Unscrew for 1-1,5 turns screws fixing the
movable bracket 3. Now brackets 3 can be moved along slots 4 and adjustment of fixture
according to dimensions of the computer is possible. It is recommended to make this placing
the computer on the platform. Adjusting up positions of movable strips 2 and brackets 3 mark
they positions by pencil. Take away the computer and screw screws fixing movable brackets 3
and strips 2. Do not apply efforts tightening screws since this can cause deformation of the
strip.
Place the computer and fix by means of fixing brackets made of stainless sheet steel.
Should fixing stand 6 with the fixing bracket hinder to operate the computer, it can be moved
into another position 7.
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 (100, 300, 500, 900 MHz, 1.5
or 2 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-pin connector. The
operation combination of the low frequency antenna 38-150 MHz is shown in Fig. 5.
Transmitting and receiving antennas are fixed to the grip via articulators those may be fixed at
angles of 0, 30, 60 and 90 degrees to the vertical. The cables are attached to the grip by plastic
clamps or adhesive band. After joining of cables in the middle of the grip they should be
fasten together by adhesive band every 10-15 cm. The method of attachment of 0,5 m (150
MHz) and 1 m (75 MHz) dipoles is illustrated by Fig. 7. To operate at frequency 38 MHz
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 Fig1.b. In
this case antenna 1 transmits but antenna 2 receives signals.
2.2. Switching ON of the Georadar.
Warning: Before switching ON the georadar please make sure that antenna is in correct
position, i.e. surface coupled antenna 100 MHz, 300 MHz, 500 MHz, 900 MHz, 1.5 GHz,
2 GHz is placed on the surface of ground or wall, but 38-75-150 MHz or 750 lWHz
antenna - in proximity to the surface of ground or wall.
Zond-12e georadar has build-in deactivating mechanism, i.e. transmitter is switched ON
only when operator enters SETUP menu item or START data acquisition. Transmitter
switches OFF immediately after operator STOP data acquisition or leaves SETUP menu
item.
1) Switch ON the georadar by means of toggle switch 7 located in the middle of the control
