This particular sbag has been disturbing the team for the oast few weeks. What could be the cause, we have replaced the control unit, antenna and also TR unit. Checked every component in the system for serviceability but it still persists.

kindly mention RADAR is installed  on your birds .

Best Regard

NOT a lot of info tto work with but IF the ground returns are only on one side of the display your ANT gyro stabilization is probably bad

What info do u need? Ask so i can provide them as required. 

 

The Radar system is a Bendix color weather radar RDR-1FBM

Few more questions:

1. Does it really paint ground or there may be some permanent targets upto some permanent elevation? In this case your radom may have some moisture accumulated inside which needs to be replaced.

2. External system providing stabilization data to the radar also needs to be verified.

3. You may place some sort of spacers (washers) under lower bolts of the antenna pedestal to elevate radar beam but aircraft leveling also to be ensured before this shortcut.
