Abstract
In the process of inhomogeneous sea clutter suppression in the case of low sample size,sparse re-construction space-time adaptive processing technique has the problem of relatively large calculation burden in large dimension of clutter measurement matrix and the complex iteration mechanism.In view of the problem aforementioned,this paper proposes a fast SR-STAP clutter suppression method.The dimension of measurement matrix is reduced via the procedure of echo space-time decoupling,and the operation burden of high-dimensional matrix is reduced.Based on the fast Fourier transform,the spectrum distribution support set is obtained and the prior matrix factors are constructed.Besides,the sparse optimization is improved and the convergence is accelerat-ed by adjusting the factor weights so as to achieve the rapid recovery of clutter spectrum.Simulation results show that the proposed method has the advantage of low complexity and reliable performance of marine target detection.关键词
