Abstract Background Space–time adaptive processing (STAP) has been widely used in the fields of communication, radar, and navigation anti-jamming. However, the traditional scalar arrays used with STAP have limitations because they can only obtain s

To address the problem that traditional direction-of-arrival （DOA） estimation algorithms did not fully utilize the signal characteristics of active decoys and radar， which led to poor angular resolution of anti-radiation missile， a single sna
