摘要
对未知LFM雷达信号进行参数估计是截获分析、分选识别及干扰实施敌方低截获概率雷达信号的前提。本文分析了雷达信号参数检测方法 WVD,并对该方法在对雷达信号检测时产生的交叉项引入了STFT线性变换进行处理。仿真实验表明,该方法在充分发挥了WVD对信号的分析处理能力的同时能有效地抑制交叉项影响。
The parameter estimation of the unknown LFM radar signals is a prerequisite for the interception and analysis,the sorting and identification and the hostile low-interception probability radar signal jamming. The radar signal parameter detection method WVD is analyzed,and the cross terms caused by the WVD in radar signal detection are processed through the linear transform of the STFT.The simulation test indicates that this method makes full use of the signal analysis and processing capabilities of the WVD,and at the same time effectively suppresses the effects of the cross terms.
