Ci vorrebbe un radar che fa un paio di scansioni ogni tot minuti, ma non credo che esista.

Intendi una cosa così?

2.23 Watchman
2.23.1 How watchman works
The watchman function periodically transmits radar pulses for one minute to check for
targets in a guard zone. If a target is found in the zone, watchman is cancelled, the audio
alarm sounds and the radar continues transmitting. If no target is found the radar goes into
standby for the number of minutes specified on the RADAR DISPLAY SETUP menu. This
feature is useful when you do not need the radar’s function continuously but want to be
alerted to radar targets in a specific area. “WTCH” appears at the top left corner when
Watchman is active.
