摘要
GPS天线阵列接收技术能有效地对抗人为干扰,其自适应算法的选择影响阵列的抗干扰性能。当有用信号的实际来向与理论估计值有误差时,自适应算法不但要求对干扰有很强的抑制能力,而且自身应具有稳健性。结合GPS天线阵列接收信号特点,从理论上分析比较四种自适应算法的抗干扰性能,得出了一种较优的算法,并由仿真实验进行了验证。
Adaptive array receiving technology can effectively restrain jamming, and its anti-jamming performance is affected by its adaptive algorithms. It requests not only strong ability of restraining jamming but also robustness in these algorithms, while signal steering vector mismatches estimated. Combining with the characteristics of GPS receiving signals, the anti-jamming performance of four its adaptive algorithms is analyzed in theory, and a better algorithm is elicited. The simulation results confirmed the theoretical anlysis.
