Main Bang Suppression Adjustment････････････････････････
The adjustment is intended for suppressing the main bang that is an echo signal from the
microwave circuit such as waveguide appearing as a circular echo at the radar video
center. It is the optimum level in which the main bang suppression is adjusted so that the
main bang remains weak on the video.
Attention
Do not change the adjusted level carelessly. If the adjustment is improper, the
target signals on the short ranges may be cleared.
Procedures
1 Set the radar range scale to the minimum 0.125 NM, set
PROCESS, TGT ENH and FUNCTION to OFF, and set the
system to the Transmit mode.
