Exploiting persymmetry for JDL-STAP

Blog Article

Joint domain localisation (JDL) is a popular reduced-dimension space-time Games adaptive processing (STAP) technique for clutter suppression in an air-borne radar system.Here, the authors develop an improved JDL method by exploiting persymmetric covariance matrix, referred to as persymmetric joint domain localisation (Per-JDL), in order to make maximum use Bar Height Table Bases of training samples and further improve the STAP performance under small training data support.The proposed algorithm is verified to be efficient in training-limited scenarios by simulation results.
