摘　　要：针对现代雷达采用复杂体制造成的不能正确识别辐射源问题,提出一种基于联合参数建模的雷达辐射源识别方法。该算法首先对辐射源进行脉冲等级和统计参数等级的联合建模,然后将联合参数模型用于识别过程中,基于特征参数的不同描述模型构建不同的识别算法,其中特征参数的联合建模思想是本方法的核心。仿真实验表明,本文方法能够实现对复杂体制雷达辐射源的建模和识别。To deal with the problem of emitter identification caused by using complex operations used by hostile radars,a new identification algorithm based on joint-parameter modeling（JPM） is proposed in this paper.This algorithm can model the emitters in both pulse-level and statistical parameter level,then the model of joint-parameters is used for identification by constructing different identification methods for different models of the emitters.The kernel of this algorithm is the idea of JPM.A number of simulations are presented to demonstrate the modeling capability and identification capability of the JPM algorithm.Simulation results show that the proposed algorithm can model and identify the complex radar emitters correctly.
