| 摘 要： | 讨论了GPS系统中自适应阵干扰抑制的问题,对比研究了最优自适应阵与基于特征空间自适应阵的抗干扰性能。通过理论推导和仿真分析,与最优自适应阵相比,基于特征空间在信号与干扰噪声比性能上略有不如,但其在理论上能够完全抑制干扰,具有更好地干扰抑制比。

| Abstract: | The adaptive array anti-jam problem in GPS system is studied.Anti-jam performance of adaptive array based on optimum algorithm and eigensapce algorithm are presented.Through the theory analyse and simulation measure,contrast to optimum algorithm,eigensapce algorithm is not so good at signal to jamming and noise ratio,but can suppress the jamming entirely and is better at jamming cancelled ratio. |
