摘　　要：导航终端的空时二维级联自适应处理(STAP)抗干扰技术涉及采样协方差矩阵的求逆运算,实际使用中往往难以满足实时性要求。针对该问题,在分析传统算法的基础上,提出了一种线性化迭代的权值更新算法。仿真结果表明该算法可在降低运算量和实现复杂度的基础上使干扰抑制性能接近最优,同时给出了该算法的一种工程实现方案。Space-time adaptive processing anti-jam techniques for navigation terminal involve matrix inverse computation,therefore the real-time performance is hardly satisfied.On the basis of traditional algorithm,a linearized weight iterative algorithm is proposed and simulated.The simulation results show that the performance of the method approaches the optimal while the computational complexity is reduced.The engineering realization method of the algorithm is also presented.
