雷达信号参数类型的图像识别法

The Image Recognition Method of Radar Signal Parameter Types

目前,国内雷达辐射源识别一般是在得到辐射源各特征参数数值及变化类型的基础上,再利用这些信息推断出辐射源的体制和用途。随着新型的、各种复杂体制雷达的不断出现,传统的雷达辐射源特征参数分析法往往不能准确得到所需参数信息,因而使得辐射源识别面临严峻的挑战。基于此,提出一种全新的参数类型判断法——图像识别法。该方法理论简单、实现容易且可以快速直观地得出识别结果,仿真实验结果表明新方法用于雷达信号参数类型判断具有实用性和有效性。

At present,radar emitter recognition is usually on the basis of getting the feature parameters＇ values and types,and then the system and usage of the emitter can be deduced by this information in our country.For the continuous appearance of new and different complex radars,the required parameter information often cannot be gained correctly by the classical radar emitter parameter analysis method,which makes emitter recognition face rigorous challenge.Considering this problem,a wholly new method of parameter type judgment is proposed in this paper,which is called image recognition method.This method is simple in theory and can be realized easily.Its recognition results can be gained fast and intuitively.The simulation experiment results show that this new method is of practicability and validity in radar signal parameter type judgment.
