| 摘 要： | 介绍了一种探测隐身目标的实现方法．以双基地雷达为例，通过讨论雷达的有效散射截面RCS与雷达作用距离的关系^1]，将接收机部署在探测隐身目标的前沿，使整个探测系统可在较远的距离上发现隐身目标．对于接收机收到的目标回波信号比较微弱，噪声相对较大，对于隐身目标的信号检测，可以采用对小信号的预处理，数据采集，进行分析处理^2]．文中给出了理论依据，建立了模型，并通过MATLAB语言进行计算机模拟仿真，给出一些结果，说明其可行性．

| Abstract: | We introduce the realization of detecting stealthy target on the basis of spread spectrum bistatic radar .The connection between RCS and the effective distance of the radar was discussed.Detection of the stealthy target from a far distance was possible.The characters of stealthy target were briefly analysed.A design of measuring amplifying circuit and a flow chart of signal collection and process were given.The signal and process of data were simulated by computer using MATLAB directly. |
