11.2 Running a survey
When starting out for a survey you should always have an idea
about the depth/time section you are about to survey. This not
only determines your depth/time section to be recorded but
also your choice of antenna frequency for the survey. One
antenna can be used for a wide range of depth surveys but it
might not possess the maximum depth resolution required for
your survey.
Starting a survey routine is a simple task with RAMAC/GPR
CUII. CUII offers you a fast way of parameter choice through
the "Pre-set" parameter settings. Factory default and user
selected parameters can be saved for later use. First-time
GPR users will find the default settings to be helpful in setting
up their system parameters.
During data collection the radar data and other information are
displayed on the computer screen. Once data collection is in
progress modifications to display functions, screen colors, gain
settings can be performed without affecting the start
parameters or the recorded data. The data collection can be
interrupted and resumed at any time. This feature facilitates
the entry of field notes and comments. For more information
see RAMAC GroundVision software manual, version 1.3.
RAMAC/GPR CUII offers you four different ways of acquiring
data. They are:
?? By the use of a distance measuring device (distance
triggered)
?? Through the external PC keyboard (by pressing the
SPACE button)
?? By taking readings at fixed time intervals
We recommend measurements be performed using some kind
of distance measuring control. This way you can relate the
