摘要
针对现有空时自适应处理(STAP)难以同时兼顾数据采样与性能,提出了一种STAP的降维矩阵改进算法,并给出了这种矩阵的具体构成。该算法的降维矩阵选取结合了局域联合处理方法(JDL)在主波束周围选取辅助通道性能稳定和广义相邻多波束法(GMB)辅助通道对准主波束选取针对性强的特点。仿真实验表明了该算法相比JDL和GMB方法在性能有所提升的同时也兼顾降低了数据采样要求。
To solve the problems of huge calculation and low performance of the space-time adaptive processing（STAP）,a reduced dimension matrix STAP algorithm was put forward in this thesis,and the construction of the matrix was introduced.The selection of the matrix combined the advantages of high stability and pertinence of JDL and GMB.The algorithm was compared with JDL and GMB,and simulation results showed that the algorithm not only reduced the calculation,but also improved the performance.
