Lost Target Alarm
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.

The alarm will sound once
when a lost target symbol is
displayed.
If the 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.
