1. RADAR OPERATION
1-94
Note 2: In the dual radar display, a guard zone set on the main radar is also
accommodated on the external radar. When the position of the antennas
for the main and external radars is different and the No. 2 guard zone is set
on a close-in range, the on-screen guard zone may be shifted slightly from
both the main radar antenna reference and external radar antenna
reference. Accordingly, on the dual radar display, the actual guard zone
area may be shifted slightly. For example, the guard alarm sounds against
a target which has almost entered the guard zone. The further the range
the smaller the shift; however, there is little shift with the No.1 guard zone
(3-6 mile range, fixed). Further, do not set a guard zone such that it
straddles a boundary line of the dual radar sector.
A g
uard zone cannot be set while the dual radar display is active. Set a zone
before activa
ting the dual radar display.
