MUTUAL INTERFERENCE
A small pulse transmitter is
mounted on the beacon which
is triggered by the vessels
radar pulse.
The mark will be displayed on
the screen only intermittently.
The true echo of the beacon
will appear on the screen in
front of the identification
signal.
Ramarks transmit pulses
continuously or to special
time schedules, rather than
on receipt of a vessel’s radar
pulse.
SARTS detect the incoming radar pulse from a searching aircraft or
ship and respond by transmitting a distinctive signal of 12 blips
extending approximately 8 nautical miles outward from the SART’s
position.
