摘　　要：常用的自适应调零卫星导航抗干扰算法,可以对干扰进行很好的抑制,但自适应调零算法会对卫星信号的相位产生扭曲,导致抗干扰处理后的卫星信号无法用于高精度定位。研究数字多波束抗干扰算法,通过对卫星方向信号约束,达到在抗干扰的同时保证卫星信号相位稳定,实现高精度定位。该算法经分析和实际采样数据仿真验证,可实现强干扰条件下卫星导航高精度定位。The commonly used anti-jamming algorithm for adaptive zeroing satellite navigation can well suppress the interference,but the anti-jamming will distort the phase of the satellite signal,resulting in that the satellite signal after anti-jamming cannot be used for high-precision positioning.The digital multi beam anti-jamming algorithm is studied.By constraining the satellite directional signal,the anti-jamming is achieved while ensuring the phase stability of the satellite signal to achieve high-precision positioning.The algorithm analysis and actual sampling data is simulated and verified.
