摘要
角欺骗干扰是脉冲多普勒雷达导引头十分有效的干扰方式,在时频域均难以找到其有效的抑制方法。提出一种利用极化滤波技术抑制角欺骗干扰的新方案。建立了全极化脉冲多普勒雷达信号模型,论述了该技术的原理及实现,并对极化滤波器性能和干扰抑制效果进行仿真。研究结果表明该方案能够实现对角欺骗干扰的有效抑制,在工程实践上也是可行的。
The angle cheating interference is very effective for the pulse Doppler radar seeker. It is difficult to find an effective suppression method of this kind of interference in time and frequency domain. This paper presents a new scheme to suppress the angle cheating interference by using polarization filtering. The full polarization signal model of pulse Doppler radar was established, the theorem and implementation of the technology were discussed, and the performances of polarization filter and the effect of interference suppression were simulated. The results demonstrate that the scheme can suppress the angle cheating interference effectively and is feasible in engineering.
