Frequently Asked Questions
Q: I was tracking a target on my radar screen and it suddenly disappeared. What
happened to it?
A: One of the most critical pieces of data for target acquisition is a stable and
correct heading value. MARPA or AIS targets are generally lost when the target
is too small, returning too weak of an echo, or the heading fluctuates too much.
If you experience lost targets on a consistent basis, you can create a recording
of your radar and send it to us for further troubleshooting. To start recording,
right click on the Radar window and select Record/Playback. Select Record, and
the software will ask you for a file name. The extension for the existing IR2 radar
is .RAD. Please zip your playback file and e-mail to support@nobeltec.com with
a description of your problem.
Q: My radar image occasionally looks “smeared”. What is causing this?
A: “Smearing” of the radar image generally occurs due to one of two reasons
which include:
1) The PC is trying to do too many computations at one time (Nobeltec
recommends using at least a 1GHz system to prevent this).
2) As the radar changes ranges, there is a transition between the previous
pulse length the radar was using and the pulse length of the new range
setting. The transition between these two causes the “smearing” to occur.
