摘要
强干扰下ＬＦＭ信号的检测与参数估计在雷达信号处理领域具有重要的应用。本文首先分析了强干扰下ＬＦＭ信号的特点，对ＬＦＭ信号的检测与参数估计方法进行了总结和比较；随后研究了ＷＨＴ法的检测性能，绘制了ＷＨＴ检测器的接收机性能曲线（ＲＯＣ）。最后，提出一种基于ＷＨＴ的抑制强干扰和进行ＬＦＭ信号检测与参数估计的方法，并给出了实验结果。
It is an important application for the detection and parameter estimation of LFM signal embeded in strong interference in radar signal processing. We have analyzed the characteristics of LFM signal embeded in strong interference, at the same time, the methods of detection and parameter estimation of LFM signal are summarized and compared in this paper. Subsequently, we investigated the detection performance and portray the ROC of WHT detector. Finally, we advance a method of restraining the strong interference , detecting and estimating the parameter of LFM signal based on WHT, and the experimental results are given.
