What is 'shadowing' on radar and how can you reduce it?

Shadowing on radar is the blind area directly behind a large target where echoes are blocked by the target itself. The radar’s beam is diverted or blocked by the tall or bulky object, so anything behind it doesn’t return to the antenna, leaving a gap in the display. You reduce it by changing the geometry: raise the antenna so the beam can pass over or around the target, which shortens the shadow region; adjust the range or the scan angle to move or illuminate the area that would otherwise be hidden; and if possible, use a different look angle or a second radar viewpoint to cover the blind spot. These adjustments help the radar see around or past the blocking object.
