Ocean reverberation suppressing by direct data domain based STAP

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 (D
³
LS) 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 D
³
LS based STAPs. Simulation results show that the D
³
JDL outperforms other D
³
LS based STAPs and statistical STAPs except optimal STAP.
