RWR Indication in the back of Patriot STR

[Ramires]

The Patriot STR has a coverage of roughly 120 degrees. But when flying behind a Patriot STR - so outside of the radar coverage - you still got a RWR indication. I can‘t imagine that radar reflection would cause an indication on RWR (if there is one?)

there are still back& side lobes to contend with. they dont create tracks for the operators, but might show up on a rwr
