    Abstract
  • A key link in space-time adaptive processing (STAP) is the estimation of covariance matrix, which depends on auxiliary samples near the sample to be detected. To ensure the estimation accuracy, sufficient independent identically distributed auxiliary samples are necessary. In this paper, the correlation of reverberation auxiliary samples, the identical distribution characteristic, and the selection of time point number are analyzed, and a corresponding valid scheme is given according to the characteristics of acoustic signal. As a result, a selection method of auxiliary samples for reverberation suppression via STAP is proposed through comprehensively considering the estimation precision of covariance matrix, the operand of adaptive processing, and the dimension-reduced STAP.
