摘要
自适应零陷技术是有效提高卫星导航接收机抗干扰能力的重要措施。针对常规的空时联合最小方差无失真响应(STAP-MVDR)算法在高动态环境下可能会出现零陷指向与干扰来向存在失配的现象,导致导航接收机抗干扰性能下降的缺点,提出基于协方差矩阵锥的空时联合自适应抗干扰算法(CMT-STAP)来实现零陷展宽,并通过均匀圆阵仿真验证所提出方法的有效性,可大大提高导航接收机的抗干扰性能。
The adaptive nulling technology is an important anti-jamming measure,which can efficiently improve satellite navigation receiver’s performance.However,in high dynamic environment,anti-interference performance degradation of navigation receiver might be leaded to by convention STAP-MVDR algorithm as the interferences move out of the nulling beam steering.In view of the shortcomings of the STAP-MVDR algorithm,a technique is proposed for null broadening based on CMT-STAP algorithm.The efficiency of the proposed method is verified through the uniform circle arrays simulation.The anti-interference performance of navigation receiver could be improved greatly by the CMT-STAP algorithm.
