某型雷达信号处理故障诊断系统设计与应用

Design and Application of Fault Diagnosis System of Radar Signal Processing

为快速、准确定位某型雷达信号处理系统故障部位,需要设计一套故障诊断系统;在深入研究信号处理系统工作原理的基础上,通过分类总结信号处理系统故障类型,依托信号处理系统硬件开发平台,采用精确单模式串匹配算法和VC++可视化编程环境,设计开发了信号处理故障诊断系统;在后续试验和设备日常维护中,该诊断系统定位数十次信号处理系统故障;结果表明,该诊断系统具有故障定位快速准确等优点,能够实现信号处理系统故障的快速维修。

To achieve fast and accurate fault location for the components in a radar signal processing system,it is necessary to design a fault diagnosis system.By analyzing the operation principle of the considered signal processing system,categorizing the types of the faults,and using the hardware development platform,a fault diagnosis system is developed via accurate single-mode string matching algorithm and VC＋ ＋ visual programming environment.In the experiments and the routing maintenance,the proposed diagnosis system exhibits the advantage of fast and accurate fault location,which enables the timely maintenance for the radar signal processing system.
