摘要
某型末制导雷达系统复杂、难于建立精确数学模型,因此采用常规方法对其进行故障诊断难度较大。而采用Multisim软件对其接收组合中的和路视频放大器电路进行仿真,再由实测样本数据训练BP神经网络的方法可较好的将故障定位到元器件级别。
The system of homing radar is complicated, and difficult to set up accurate mathematical model, so it is hard to diagnose the fault adopting the conventional method. But the method which uses Muhisim software for circuit simulation of video frequency magnifier of ＂and＂ route in receive combination, then trains BP neural network with sample data can preferably localize fault to components.
