多/双基地雷达检测计算机仿真

Computer Simulation of Multi / Bistatic Radar Detection

本文利用分布式检测方法，研究了多／双基地雷达联合检测的计算机仿真技术．仿真检测对象为ＳｗｃｒｌｉｎｇⅠ、Ⅱ、Ⅲ、Ⅳ型非相干起伏目标．各本地接收机输入端的信嗓比可按预定的分布随意装定．被仿真的接收系统米用对数中放、线性检波及视频积累处理．中央处理器的判决方式、各中放的对数特性参数、检波参数及积累脉冲数均可随意键入．建立了四类起伏目标的随机序列与色高斯噪声混合的仿真模型．编制了全系统检测的仿真软件，并在互ＢＭ４３８１计算机上对五个多／双基地雷达的联合检测作了仿真实验．结果提示，采用多数表决，可望在７５％发现概率处，获得较单站检测时高３ｄＢ以上的信噪比改善．

Computer simulation is studied for distributed detection of multi/bistatic radar system which consists of a number of physically separated peripheral receivers and a central processor.The detection process of the radar system is modeled by the computer IBM 4381.In the computing model all the peripheralreceivers are supposed to have the same stlvcture and performance, including noise figure. bandwidth.ambient temperature and detection threshold level.The peripheral receiver comprises a logarithmic iF amplifi...
