1. Introduction
Thank you for your purchase of our radiolocation subsurface sounding equipment and/or
your interest therein. Our Company is using over 30 years of experience in this field; the studies
in this field were launched by Aviation Subsurface Radiolocation Problem Laboratory (PLAPR)
legally succeeded by Radar Systems, Inc.
A modern Ground Penetrating Radar (GPR or “georadar”) is quite a sophisticated radio
engineering device. But with introduction of microprocessor and computer technologies, it has
become simpler in operation as compared with early models. Skill to operate a georadar actually
means knowledge of how to use the software what description you are reading now. Take a look
on software operation, and you'll find no difficulties in it.
In many cases, correct interpretation of sounding data results from certain experience
which you have already or which, hopefully, you'll acquire quite soon. The software will be your
effective helper for your tasks and decisions.
Prism2 Software Package is designed to be used in field as a component of Zond-12e
and/or Python Georadars and also in laboratory for radiolocation sounding data processing and
interpretation. Important: to work with Zond-12e and/or Python Georadar, computer must be
equipped with Ethernet card 10/100 BaseT. For wireless connection computer must be
equipped with Wi-Fi card.
The tasks of Package include:
1. Control of all Georadar modes, and adjustment of its parameters for specific job
conditions.
2. Receiving digital data from Georadar in a radiolocation sounding run, and recording
them in data files on a computer hard disk.
3. Visualization of data being received (or received earlier) on a computer display in
user's specified mode.
4. Digital processing of received data for extracting useful signals and suppressing noise,
interference and non-informative signals.
5. Determination of various signal parameters, spectral computations, and the like.
6. Printout of results.
Package is supplied on USB Flash card, CD or online from the manufacturer web site
(http://www.radsys.lv) with the computer installation file (SETUP.EXE).
Package is compiled as a user's integrated medium, i.e. user starts PRISM2.EXE file only
and deals only with this file. All and any other auxiliary files are run automatically as a function
of user's actions.
The application has a multi-window interface which is convenient for comparison of
various profiles, e.g. before and after processing, single section covered using different antennas,
etc.

2. Brief Description of Georadar
Georadar is quite a sophisticated engineering device. Below, its simplified structural
schematic is presented, which allows getting a general idea of its principle of operation but does
not reflect its complexity.
Fig. 2.1. Simplified structural schematic of Georadar.
The transmitter sends extremely short electric pulses exciting the antenna. The transmitting
antenna radiates ultra-wideband one-and-half-period electromagnetic waves, their approximate
shape is shown in Fig. 2.2.

Fig. 2.2. Shape of radiated electromagnetic wave.
These electromagnetic waves are propagating in sounded medium, thus reflecting from
various inhomogeneities (metals, cavities, various objects, layer boundaries with different
parameters, etc.). Reflected sounded waves which carry information on the medium being
sounded are received by the receiver using a receiving antenna. Receiving signal however, in
addition to reflected wave also contain a direct wave that is going by the shortest distance
directly from the transmitting to the receiving antenna. Therefore, the receiver's output signal is
combination of transmitter's pulse (as shown in Fig. 2.2) followed by reflected pulses. This
transmitter's pulse should be used as a starting point for estimating a delay of reflected signals
for the purpose of determining the target's depth of occurrence in the medium.
Fig. 2.3. Example of received signal.
Transmitter pulse is clearly visible to the left.
Passing process shown in Fig. 2.3 is very fast, and takes tens to hundreds of nanoseconds
which in technical terms makes him very difficult to process. Therefore stroboscopic converter is
used to "expand" this process in time. Synchronizer is used for controlling all Georadar
assemblies operation, while in its turn synchronizer, is controlled by the “Prism2”software
from your computer, and its description you are holding in your hands right now. Computer
running “Prism2”is the one that receives radiolocation sounding data delivered from GPR.
When analyzing received data, it is important to keep in mind that the propagation speed of
electromagnetic waves in sounded medium (other than air) is not equal to the velocity of light, in
fact –its velocity is less due to the square root of the sounded medium dielectric permittivity.
Consideration of this factor in the software is made automatically, and you will see it soon by
yourself.

3. Convention of Terms
Some terms that are present this text are listed below, since they have different
interpretations in various literature sources.
1. Sample: Unit value comprising reflected signal amplitude at a definite time.
2. Trace: A set of samples comprising one-dimensional information about reflected signals.
Examples of traces are shown in Figs. 2.3 and 4.1.
3. Profile: A set of samples comprising two-dimensional information about reflected signals
generated while passing a survey line. A profile may contain any quantity of traces. Profile
examples in various types of display are shown in Figs. 4.2 and 4.3. The final result of
sounding shall be a profile (or a certain number of profiles) as a file (or files). Subsequent
steps will be data processing (if required), printout (if required) and interpretation.
4. Zero point: Trace sample corresponding the time of transmitter’s maximum emission. It is
this very sample that has zero number on the scale along the traces, i.e. reflected signal’s
delay time should be counted from this sample. As mentioned above, the transmitter’s pulse
is approximately a one-and-half-period (i.e. three-lobe) signal. Therefore, zero point should
be set to the second lobe of the transmitter’s pulse. The Zero point setting procedure is
described in Section 10 of the present User’s Manual. It is a rather important parameter
which must be considered when measuring the time delays of signals to determine target’s
depth in the sounding medium. Zero point location examples are shown in Figs. 4.1, 4.2, 4.3.
5. Wiggle plot: Way of profile display where traces are running vertically with some spacing
between them. Drawing of each trace is made by a curve deviating to the right or to the left
from the trace centerline, depending on the sample value in each point of the trace. Here,
positive half-waves are painted in the color corresponding to the maximum positive level of
the color scale selected. Examples of wave profile are shown in Fig. 4.2.
6. Line scan: Way of profile display where traces are running vertically close to each other
and are drawn by vertical lines. Color in each point of a line shall depend on the amplitude
of a respective trace sample conforming to the color scale selected. Examples of density
profile are shown in Fig. 4.3.
7. Mark: Distinctive feature of any profile’s trace, designating certain uniqueness of a given
trace and therefore of a given point of the survey line. Marks are used to bind a profile to the
terrain. In the course of sounding, you may press a button to enter marks when passing
certain landmarks on terrain or pre-located stations. Further on, when the profile is
visualized on a display, these marks will be shown together with the profile. Mark display
examples are shown in Fig. 4.3.

Fig. 4.1. Trace display example.
Fig. 4.2. Wiggle plot profile display example (black-and-white and color scales).
Fig.4.3 Density profile display example (black-and-white and color scales).
Note: Our experience shows that usually the most informative sounding data display type
is the density profile in the black-and-white scale (see Fig. 4.3, left side).

Note 2: Starting from 2015 in “Zond-12e” (with serial numbers from 0537) and
“Python-3” (with serial numbers from 0027) GPRs contain internal network router with
complex operation system. You need to contact with our customer support before you try to
change any of GPR’s Wireless network settings! For earlier versions of GPRs has less
complex network device, in Appendix B you can find how to change some of their settings.
Note 3: While connecting to your GPR via cable on some computers, you will have to
disconnect from any Wi-Fi connection, or disable “Wireless Network Connection” on your
device completely.

6. First Run
You will see four items in the menu after software’s starting up:
Fig. 6.1 “Prism2”Menu at first run.
The default software operating language is English, which is set after installation (there are
English, German, Russian, Greek, Korean and Chinese languages). If you wish to change it, to
Russian for example, select View/Languages menu and press the button Add language. Select
file Russian.lng. Now, you may set Russian as the default language by pressing Set as default
button. You could choose the selected language by OK button click or by double click on it.
You may choose positioning method with Radar/Positioning menu help. Possible
positioning methods are: Manual, Wheel, GPS and Wheel + GPS. Manual positioning method
allows entering of manually measured length of the passed track when you save the data to hard
drive, or by using Output parameters menu (see Section 10 below). For the Wheel positioning
you have to enter following parameters: the wheel’s diameter, the number of pulses per
revolution and trace spacing (dX), or to calibrate the wheel by moving on the precisely measured
distance. To calibrate the wheel enter Radar/Positioning/wheel menu item and click on the
small window Wheel calibration. In appeared dialog box press Start button and move antenna
with the wheel on the precisely measured distance, then press Stop button and enter the distance.
During by the wheel positioning current length of the passed distance is calculated, gathered
value is recorded to the each trace. Data will not be collected while antenna is not moving. Here
in dialog box you may chose automatic X-interpolation to display traces during data

15
acquisition equidistantly with preset spacing. You can enter trace spacing every time before data
acquisition or keep entered in dialog box value the same for all acquired data.
When using Zond-12e Advanced, the wheel operates as a two-way device. When the
antenna moves forward the profile on the screen is displayed from left to right, but if after a stop
the antenna moves backward, the profile will also be built backward, i.e., from the right to the
left and is shown as a white vertical marker. If the antenna moves backward along the same path,
then visually on the screen it will look like a back movement of the white vertical mark over the
profile. This function of the wheel is very useful at determining precise location of underground
utilities when upon moving backwards the white vertical mark precisely coincides with the top
of the hyperbola.
Should you like to use the global positioning system (like GPS), you are to choose the
receiver providing digital output of coordinates in format NMEA 0183 (Version 1.5 or higher).
Connection to computer is possible via COM port (including Bluetooth) or USB if it is defined
in computer as COM port after installation. In case of use of GPS there will be recorded in the
heading of each trace current latitude and longitude which are further used to calculate the length
of path passed and of current coordinate of the trace on the profile. In combined Wheel + GPS
positioning there will be recorded in the heading of each trace current latitude and longitude but
length of path passed is calculated by wheel.
If you need to recalibrate the wheel press Recalibrate button and repeat described above
actions.
In Radar/Where to save option, you may specify a directory wherein your sounding data
files will be recorded automatically.
In principle, the software is now ready for the work with Georadar and sounding data files;
for you to be ready as well, get familiar with functions of Menu options described in the Section
below.

Zoom in –selected area magnification.
Zoom out –reverse Zoom in operation.
Fit profile –fitting of the whole profile in one window.
Average spectrum –average signals’ spectrum calculation in a selected area before its
amplification or after they have been gained.
Trace inspection –this option is showing separate profile traces (see Fig.4.1.), it also
allows choosing which curves will stay visible in Trace window (wiggle trace, power
curve, attenuation curve).
Sample inspection–output samples of the same number along profile.
Cut traces - this option is deleting undesirable traces from the data file.
Hodograph –solving a problem of layer-by-layer ground thickness and permittivity
determination using the common depth point within a flat layer model.
Annotations –creating, deleting and editing profile annotations.
Pulse delay adjustment –adjustment of sounding pulse position on time axis.
Lines color –color selection for marks and synthesized hyperbola line.
Marks –adding, deleting and ranking marks on the profile.
Output parameters –profile display parameters output such as Output range, Length of
profile, Output view, Normalizing factor and file heading stored (Text information). You
can also switch on or off displaying of markers and annotations at the profile or leave
annotations only as the final result of probing results interpretation.
GPS Tracker - survey path applying GPS positioning display.
GPS Coordinates Table –display current profile’s editable GPS coordinates table.
Convert to UTM coordinates –latitude / longitude coordinates conversion into UTM
coordinates.
