为满足未来综合电子战的需要,提高雷达的战场生存能力,提出一种基于抗脉内识别的雷达反侦察方法。在不降低信号功率的条件下,从雷达侦察技术的角度,利用WVD时频分析作为雷达反侦察抗识别的效果分析工具,通过对几种复杂雷达信号识别效果的仿真,研究雷达辐射源信号形式和参数变化对识别效果的影响,探寻具有优良反侦察效果的信号形式及变化规律,为雷达反侦察研究提供新的思路。

In this paper,a counter-reconnaissance measure of radar based on counter in-pulse character identification is presented in order to satisfy the needs of future integrated EW and improve survivability of radar in battlefield.Under the condition of non-reduced signal power,from the view of radar reconnaissance,WVD time-frequency analysis is chosen as an effect analysis tool of count-discrimination to radar signal.By simulation to several kinds of complicated radar signals,the influence of discrimination effect brought by changing of signal forms and parameters is analyzed,and the signal forms which have excellent count-discrimination and changing rules are sought for,which offers a new idea on the research to radar count-reconnaissance.
