中文摘要：
基于雷达信号特性及归一化窗S变换与TT变换原理,提出一种新的雷达回波信号二维时频滤波方法。通过对雷达信号进行归一化窗S变换时频滤波,滤除高频杂波和随机噪声;再利用TT变换滤除低频杂波。实验结果表明,相较于传统滤波,所提方法的滤波算子随时间及频率同步变化,克服了传统方法受使用条件限制的缺点;有效滤除杂波的同时保留原信号特征,增强了检测及识别能力。
英文摘要：
Based on the characteristics of radar signal and principle of the normalized window S transform（NWST） and TT-transform,this paper proposed a new two-dimensional time-frequency filtering method for radar echo signal.First,this method used time-frequency filtering based on NWST to filter out high frequency noise and random noise radar signal.Then,it used TT-transform to filter out low frequency noise.The experimental results show that,compared to traditional filter,the filter operator of the proposed method synchronously changes with the time and frequency to overcome the shortcomings of traditional method by the use of conditions.At the same time,this method can effectively filter out the noise while retenting of the original signal characteristics,so that enhance detection and recognition ability.
