Lost Target Alarm - JRC JMA-9832-SA Instruction Manual

......Lost Target Alarm

Attention
If the radar tuning, gain, sea clutter suppression, rain/snow clutter suppression are not adjusted
adequately, the lost target alarm may be easily generated. So such adjustments should be mad
carefully.
When it is impossible to continue tracking any acquired and tracked target, the LOST target alarm will
be generated. The typical causes for alarm generation are shown below, but not limited to the following:
• The target echo is very weak.
• The target is shadowed by a shore or a large ship and its echo is not received.
• The target echo is blurred by sea clutter returns.
