The space-time two-dimensional filter weight is decided by the evaluation of the clutter covariance matrix. From the MSAR echoes model, a method of raw-data simulation in the frequency domain by two-dimensional FFT is proposed and the evaluating of MSAR clutter space-time covariance matrix is made. The simulation result shows that the data produced by this method retain the reality of MSAR space-time clutter characteristic with lower computational complexity. %K 合成孔径雷达 %K 空时自适应处理 %K 二维FFT %K 原始数据模拟 %K 空时协方差矩阵 %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=B5EDD921F3D863E289B22F36E70174A7007B5F5E43D63598017D41BB67247657&cid=B47B31F6349F979B&jid=67CDFDECD959936E166E0F72DE972847&aid=3D4BF2EB3449F6C71E0B53A7C943B93B&yid=67289AFF6305E306&vid=96C778EE049EE47D&iid=B31275AF3241DB2D&sid=DBEE434FCBFED297&eid=CFBDB06850C21CC6&journal_id=1002-1175&journal_name=中国科学院研究生院学报&referenced_num=0&reference_num=8
