摘　　要：针对机载、舰船、车载等复杂情况下电磁辐射信号识别问题,结合多种不同电磁辐射环境的研究先例,使用数学推导和模型构建方式,简单分析了PCB辐射、电机辐射、雷达泄漏和通信信号的电磁辐射特征,基于解析方法和近似方法建立了四种电磁辐射信号的数学模型。电磁辐射信号识别应用实例表明,数学模型产生的信号可替代信号采集手段更方便、快捷地进行电磁信号识别。由于电磁辐射信号在空间中传播时可能会发生非线性叠加的情况,实际使用时要根据现实因素进行数学模型调整。Aiming at the identification of electromagnetic radiation signals in complex situations such as airborne,ships and vehicles,combined with a variety of research precedents in different electromagnetic radiation environments,mathematical derivation and model construction methods are used to analyze the electromagnetic radiation characteristics of PCB radiation,motor radiation,radar leakage and communication signals.Based on analytical and approximate methods,mathematical models of four electromagnetic radiation signals are established.The application examples of electromagnetic radiation signal recognition show that the signals generated by the mathematical models can replace signal acquisition means to carry out electromagnetic signal recognition more conveniently and quickly.Since the electromagnetic radiation signal may be nonlinearly superimposed when it propagates in space,the mathematical models should be adjusted according to actual factors in actual use.
