摘　　要：介绍了一个采用被动侦察体制的多传感器侦察系统。在研究了地面战场典型目标的噪声场和地震动场产生机理的基础上 ,对战场目标噪声信号和地震动信号进行功率谱估计 ,分析了各种目标的线谱特性。设计了拓扑结构合适的 BP神经网络分类器 。This paper describes a multi sensor surveillance system,which uses passive detection theory.The mechanism of generation and propagation of radiated noise and seismic signal of typical targets on battlefield is presented.The spectrum of radiated noise and seismic signal is estimated and its linear spectrum property is analyzed.A suitable BP neural network,which uses the spectrum of radiated noise and seismic signal as input,is designed to identify target effectively.
