Ocean reverberation suppressing by direct data domain based STAP

摘要

A class of direct data domain based space time adaptive processing (STAP) method for ocean reverberation suppressing is studied. The original direct data domain least square (D³LS) STAP does not use statistical information of the testing snapshot. This work proposes a new method named direct that the snapshot number has no effect on the performance of D³LS based STAPs. Simulation results show that the D³JDL outperforms other D³LS based STAPs and statistical STAPs except optimal STAP.
