Working with the Master Project File (Optional)
The SIR 20 incorporates a Master Project collection scheme that is intended to streamline data collection.
It is intended for use in application where all data area collected with common settings. The master
project is created by you just like any other project, but it is saved into the Master Project file in the
SIR 20 program. It is then automatically recalled at the beginning of each collection. Upon recalling the
master project, you will have the opportunity to change its name. This will not re-name the master project
file, but will become the root name of all of the data files that you collect going forward.
To use:
1
Create a data collection project as described in the previous section. Take note of the location where
that project is saved.
2
Minimize or close the SIR 20 collection program and copy that project file and the macro to:
C:\Program File\GSSI\RADANXP\Master Project. Make sure the macro copies as well. For example,
if you called your project TEST, you will need to copy TEST.RPJ (project file) and TEST.CMF
(macro) to the master project file. You can rename it at this point if you wish, but make sure both files
have exactly the same name.
3
When you wish to use the master project, open the SIR 20 collection program and click the Run
Master Project icon located at the bottom-left of the screen.
4
Enter in a new name if you wish. The data files will be saved to the working directory.
5
Collect data as normal.
The File Header
A file header is an integral part of each data file. It contains all of the radar system acquisition parameters
at the time of data collection. The file header comprises the first 1024 bytes per channel of a *.dzt file.
The primary purpose of the File Header is to record and preserve the data acquisition parameters used to
collect the data.
While all of the entries in the Header may seem intimidating at first, after you have worked with GPR
data for some time, you will find yourself gaining a full understanding of all of the different pieces of
information that it contains. Some of this information can be edited after collection to correspond to post-
processing changes or for report generation. In addition, the file header can include field information such
as location, client, date, job number, surface material, or other information useful in characterizing a site.
