重排算法在多目标雷达信号分辨中的应用

本文使用１５年前由柯德锐等人首次在谱图中使用，并经弗朗克斯等人改进并推广的重排算法，对多目标雷达信号进行架次识别，此重排算法简单且极易实施，在重排后失支双线性时，却保持了其他许多可取特性，并换回了Ｃｈｉｒｐ信号和冲击信号的准确定位，针对编队多目标雷达信号的线性调频特点，利用此重排算法在权衡能量聚集性和消重排振荡的同时，实现了对编队多目标雷达信号的分辨。

An Implementation of Radar Signal Time-Frequency Representation by the Fast Reassignment Method

In this paper we use the reassignment method in radar signal which was first applied 15 years ago.The reassignmetn method which was derived and developed by kodera,Genclrin and et al,is used to recognise radar signal in this Paper.Althoagh the method has lost Linearity,it can retain most of its advantages such as easy implementing,perfectly localized Chirp and Impulses.The multi object classification can be realzed Using LMP Characteristics of radar signal.The method is easy and practical and still consist many of the representation properties except its bilinearity,and return th0.e perfectly localized Chirp and Impulses.Using the LMP characteristic of the radar signal,we can realize the multi object classification easily.
