摘要
自适应调零天线是有效提高卫星导航接收机抗干扰性能的重要措施,具有十分重要的应用价值和发展前景。研究了一种基于LCMV准则的自适应波束形成算法,对均匀线阵和面阵都做了算法仿真和性能分析,仿真结果表明:该算法能更好地抑制多个干扰信号、保留期望信号,大大提高了卫星导航接收机的抗干扰性能。最后针对该算法的工程实现边界条件进行了分析,并提出了两种解决方案。
The adaptive hulling antenna is an important anti-jamming measure, whichcan effi- ciently improve satellite navigation receiver＇ s performance, and hasimportant applicationvalue and development prospect. Anadaptive beamforming algorithm based on LCMV criterion is stud- ied. The algorithm is stimulated and analyzed for the uniform liner array and the uniform plane array. The simulation results show that the proposedalgorithm can suppress multiple interfer- ences better, and greatly improves the anti-interference performance of satellite navigation receiver. Finally, the boundary conditions which facilitate the engineering realization of the algorithm are analyzed, and two solutions are presented.
