An improved ATI method on airborne SAR ground slow moving target detection

Based on airborne dual channel SAR, this paper improved AT I technique, put forward a weighting factor from DPCA to AT I to improve ground slow velocity moving target detect capability, the method integrated the advantage of DPCA and ATI technique, using the weight value received from DPCA to weighting process the result of interferential ATI, further more, bringing forward a new moving target detect method. The outcome of computer emulation indicates that compared with ATI method, this paper´s method can effectively decrease false target number and detect feebleness target efficiency. Compared with DPCA method, it can detect slower moving targets which DPCA cannot detect because of excessive counteraction.
