摘　　要：自适应调零天线能有效提高卫星导航接收机在复杂电磁环境中工作的可靠性,因而被广泛应用于现代武器装备中。基于功率倒置算法仿真研究了干扰数目、干扰角度、干扰功率等因素对自适应调零天线抗干扰性能的影响程度,为建立更加完善的暗室和外场测试方案提供了理论依据,同时也为对抗自适应调零天线提供了一种思路。The adaptive nulling antenna is widely used by modern weapon equipment because of improving reliability of satellite navigation receivers in complex electromagnetic environment. The influence degree is studied in the view of the number,elevation and power of interference source based on PI algorithm. It provides a theoretical basis for darkroom and outdoor test scheme and is also a way of confronting the adaptive nulling antenna.
