摘　　要：自适应调零天线技术能够在干扰信号方向产生零陷,以抑制干扰信号,有效地改善卫星导航接收机的抗干扰性能。在分析功率倒置自适应算法原理的基础上,基于LMS算法完成四元方形阵和四元Y形阵的抗干扰仿真,验证自适应天线阵的抗干扰性能,为后续研究工作提供基础。Adaptive nulling antenna technology can produce zero-sink in the direction of interference to suppress interference and effectively improve the anti-jamming performance of satellite navigation receivers.Based on the analysis of the principle of power inversion adaptive algo⁃rithm,the anti-jamming simulation of four square and four Y-matrix is completed based on the LMS algorithm,which verifies the anti-jam⁃ming performance of adaptive antenna array and provides a basis for the follow-up research work.
