一种非均匀环境中鲁棒的STAP算法
Robust STAP Algorithm in Heterogeneous Environment
摘要
Abstract
According to the performance loss of STAP caused by the heterogeneous environments, a new structured STAP algorithm is proposed. In the new algorithm, the clutter-plus-noise covariance matrix is formulated by taking advantage of the known structure of ground clutter and parameters of system. The structure of the so called structured matrix then undergoes several adjustments via taper matrices and is employed to calculate the space-time weight vector. Since the covariance matrix is not estimated directly using the sample vectors, the impact of heterogeneous environments is negligible in this procedure. Experimental results from a three-channel airborne radar are employed to verify the outstanding detection performance and robustness to heterogeneous environment of this algorithm.关键词
