9. Radiolocation Sounding Run
Once you have set all of the required parameters in Radar option menu and made all
needed Georadar adjustments, you may start sounding.
Using option Radar/Where to save, you may choose a directory for recording files
created in the course of sounding. It is advisable to save profiles related to the different
Georadar job in a separate directory to avoid confusion afterwards.
Now, place antenna (antennas) in the working position at the initial point of a
suggested survey line, and exit the Georadar Adjustment dialog box.
When Georadar Adjustment dialog box is closed it will you will see Data Acquisition
dialog box that has control buttons at the bottom. Right now, only the four highlighted
control buttons are accessible, i.e. Setup, Start, Exit, and Palette. Using the key Palette
you can select received data displaying color. Make sure you have chosen correct
positioning that is displayed in informative window at the top of the screen. Button Start is
automatically selected upon entering the Data Acquisition dialog box. Press Enter or
Spacebar to start data acquisition, if Save profile on HDD option is selected, you will be
prompt to enter the file name before process start.
Right after a 0.8 second delay audio signal “Let’s go” will be generated (if option
“Sounds” is selected) notifying that the sounding process has started. Now in real-time on
the screen radiolocation profile will be displayed. Trace signals are simultaneously
displayed in the right side of the screen.
On the top of the screen additional information is displayed about number of
acquired traces, positioning mode, distance (in case of positioning by wheel) and internal
battery voltage (only in Zond-12e Advanced). When the battery level is too low warning
message appears on the screen.
Bear in mind that using positioning by weal data acquisition is performed only
when the wheel is rotating. When the weal stops, data acquisition will be stopped as well.
Once data acquisition is started Stop, Mark and Pause control buttons become
accessible and Mark button will be automatically selected. Without selecting any other
control button, pressing Enter or Spacebar in data acquisition will place Marker on the
current trace (it will immediately become visible as a vertical line with a number of
marker) and audio signal (“Mark”) will be generated. Notice that the first trace will always
be assigned as mark 0, while the last trace will always get the mark with the highest
number.
Pressing Esc or activating Stop control button (by press Enter or Space while it’s
activated) will end data acquisition. Audio signal (“Stopped”) will be generated and Setup,
Start, Exit, Save and Palette control buttons will become accessible while Save button
will automatically be selected.
Now you can save received data by pressing Enter or Space with Save control
button activated. You will be asked to enter profile length (if manual positioning), profile’s
Y-coordinate (if 3D surveys), movement direction (towards or backwards) and a file name
that you may leave as is or modify if you need, you can also chose not to save received
data as an alternative. If the folder where you are saving your file for any reason contain
file with the same name that you are currently typed, application will suggest to
Overwrite, Add or Cancel.
It is also possible to save the obtained data when exiting Data Acquisition dialog box
by pressing Enter or Space when Exit option is selected. In this case, received profile
shall be automatically displayed in a separate window on the screen named Profile 1. Now,
you may save it by selecting File/Save as option in the Main Menu.
