Wigner-Ville变换在抗箔条干扰方法中的研究

在雷达跟踪空中目标时,受箔条干扰信号的影响,会造成雷达探测的数据不完整、不精确、不可靠.针对这一情况,本文应用Wigner-Ville变换理论,给出了一种对雷达回波信号进行滤波的算法.通过仿真实验证明,应用Wigner-Ville变换能较好地抑制箔条干扰信号,可进一步提高雷达系统的跟踪精度和可靠性.

The application of wigner-ville transform on the suppressing chaff-interference

When the radar tracks the aerial target,it is easily jammed by the chaff signals,so it will make the data detected by the radars half-baked,imprecise,unreliable and even contrary.In this case,this paper put forward an algorithm to filter the echo signals of radar through the application of the Wigner-Ville transform theory.The simulation testify that Wigner-Ville transform has a better performance in suppressing chaff-interference signals,further more,it can improve the tracking accuracy and reliability of the radar system.
