GPS单孔径双极化天线抗干扰算法与性能分析

Algorithm and Performance Analysis of GPS Single Dual-polarized Antenna Anti-jamming

设计了一种利用单孔径双极化天线进行GPS自适应抗干扰的方法,并对算法的性能进行了详细的分析。新方法在不降低卫星信号质量的前提下,仅占用单个天线位置,就可以对付窄带或宽带干扰,为增强安装受限装备的导航抗干扰能力提供了一种新的解决方案。仿真结果表明,新方法可行、有效。

A more efficient adaptive GPS anti-jamming algorithm is designed by utilizing single dual-polarized antenna and its performance is discussed. While keeping intact the quality of the expected navigation signal, the new algorithm is able to do with either narrow or wide jamming while only occupying a single antenna position. Therefore, the new algorithm presents a better solution for improving anti-jamming ability of the small volume equipment. Simulation result shows that the new algorithm is feasible and efficient.
