Rejecting radar interference
The Interference rejection (IR or Interf. rej.) option is used to
eliminate second trace echoes from far distance targets, and the
interference from radar units operating in the same frequency band.
When the IR is ON, transceiver pulse staggering is enabled. When
enabled, the transceiver PRF is changed slightly for each sweep. By
doing this, spiral interferences and second trace echoes are split in
range from sweep to sweep. The IR processing clears all the echoes
found at the same range if they are not present in each sweep.
The IR must be chosen according to the environment around own
ship:
•
IR off when the maximum signal from the receiver is needed
•
IR on when the interference or second trace echoes disturb the
radar image
To avoid missing weak targets, the interference rejection should be
set to OFF when no interference exists.
Target separation
Controls the target discrimination of the radar (separation between
objects is more prominent).
Fast scan
Sets the speed of the radar antenna rotation. This option gives faster
target updates.
Ú Note:
Maximum speed may not be achieved depending on the
radar Settings, Mode, and Range selected. The radar will only
rotate as fast as the current control settings allow.
Target boost
The target boost control increases pulse length or reduces radar
bandwidth to make targets appear larger in range and increase
radar sensitivity.
More options
Menu options can vary depending on your radar's capability.
