If a contact file already has the same primary name as the XTF file and
the CON/XTF pair reside in the same directory, the system properly pairs
them for processing.
It’s a good idea to select (highlight) all applicable contact files at
one time for processing. That way, the system can determine
the best order to process the files. This speeds up the
processing. Also, the visual representation of the target in the
two windows (showing the target’s geographical position and its
along-track position) will appear to be more precise. Even so,
the visual representation is merely suggestive; after all
computations have been done, you end up with the same
numerical latency value whether you manually specify the order
of con files to process, or whether you let the system determine
the processing order.
4. Click Settings if you believe you need to fine-tune some of the
parameters that will be used during processing. See ‘Fine-Tuning Settings
to Get Better Hyperbolas’ for details.
5. Click
Compute.
The system computes the hyperbola(s) for your contact file(s). As this
happens, messages relevant to the con file currently being processed
appear in the status box next to the Close button. When processing of
each contact file finishes, the system places a thumbnail of the hyperbolic
image in the window of processed files. A larger, separate child window
displaying the hyperbola being built also appears at this time.
6. If you are selecting your contact files one at a time, repeat steps 2
through 4 to compile a collection of hyperbolas for contact files.
Figure 60 shows a typical end-state for a completed latency test of
sidescan sonar data CON/XTF pairs of files. The most important piece of
information that results from the processing is the latency value
(1884.1 ms in the displayed sample).
