摘要
在现代战争中,各种体制的雷达在复杂的电子环境中必然受到来自敌方的各种干扰。欺骗式的距离拖引干扰是一种常用的危害性较大的有源干扰方式。为了能对干扰采取相应的对抗措施,必须对它进行及时而有效的检测。在分析距离拖引干扰的基本原理和利用小波分析进行检测的理论基础上,建立了雷达的测距模型,提出了用小波分析进行距离拖引干扰检测的方法,并进行了仿真实验。结果表明该种检测方法不仅可以有效判断干扰是否存在而且可以对其进行精确定位。
In the modern war, with the rapid development of electronic countermeasure technology, the radars of different systems would he suffered various kinds of jamming from enemy in the complicated electronic environment. RGPO is a kind of widely used active jamming with greater harmfulness. Jamming prompt and effectively must be detected in order to take the corresponding countermeasure to it. In this paper the basic principle of RGPO and the theoretical foundation of wavelet-based jamming detection were introduced, then the distance detecting mode/of radar was ,set up and the method of wavelet-based detecting RGPO was proposed. The simulation results indicated that the method can not only estimate the jamming effectively but also locate it accurately.
