Description
Summary:This paper presents the hybrid algorithm of SigmaDelta-STAP and direct data domain(D 3 ) which is robust to the discrete interferer. SigmaDelta-STAP provides high performance result with the relatively low complexity of calculation. It also requires small number of training sample to estimate covariance matrix. However this algorithm is vulnerable to the discrete interferer which is target-like interferer with high SNR. This paper shows that SigmaDelta-STAP can suppress discrete interferer signal in conjunction with direct data domain (D 3 ) method which is an effective method to eliminate non-correlated interference such as discrete interferer in the non-homogeneous environment.
