单脉冲自动跟踪系统故障诊断仿真研究

Simulation Study on Fault Diagnosis of Monopulse Automatic Tracking System

接收天线的自动跟踪系统运行过程中常常会出现故障,传统的故障诊断方法极大地依赖技术人员的维护经验且效率较低;提出了一种基于Systemview的故障诊断方法,分析了影响自动跟踪系统性能的主要因素,以单通道单脉冲跟踪接收系统为例根据实际接收系统进行建模,给出了影响跟踪系统性能三种主要因素对应的仿真分析方法;仿真结果表明,该仿真分析方法能准确定位系统故障,将有效地增强跟踪系统的可维护性。

The tracking system of antenna often goes wrong and can＇t track signal automatically. The conventional methods for fault diagnosis rely heavily on the experiences of the engineers and furthermore have poor efficiency. The article introduces a new method for fault diagnosis based on Systemview and analyzes the major three factors, which influence the performance of the system. According to the practical system, the track system is modeled and the simulation methods in each situation are also given. The results of simulation indicate that this method can locate the fault accurately and strengthen the maintainability of the track system effectively.
