某型制导雷达故障的致因因素灵敏度分析

Failure Key Factors Sensitivity Analysis on A Certain Type of Guidance Radar

某型制导雷达是该型地空导弹武器系统的重要组成部分,是该武器装备仿真系统中的主要建模对象。导致该武器系统发生故障的不利因素多种多样,而且其中一些因素之间存在着耦合性,给捕捉故障发生规律带来困难。基于该型制导雷达已有的故障信息统计,对导致故障的致因因素及其相互作用进行了分析;分别建立了导致该型制导雷达故障的单因素、双因素和多因素灵敏度计算模型;选择导致该型制导雷达发生故障的典型因素进行了计算分析,通过控制模型计算的输入/输出参数变化,得出相关因素导致故障发生的规律。通过建立科学合理的故障致因因素体系,对故障致因因素进行灵敏度分析,有助于仿真模型的精确描述,提高地空导弹武器系统的可信度和可用性。

A certain guidance radar is an important part of the SAM weapon system,which is the major modeling objective in the weapon system simulation.There are various negative factors leading to failures,and some of them are coupling with each other,which can cause the difficulty in capturing the occurrence rules of failure.Based on the existing failure information statistics,unfavorable factors and their interactions were analyzed.Single factor,two-factor and multi-factor sensitivity calculation models were set up respectively.The typical factors were analyzed and calculated which caused the radar failure,drawing the conclusion of the failures’ rules by controlling the input/output parameters of the model calculation.Establishing a scientific failures’ key factors system and analyzing sensitivity of the failure causes may be of great help in precise describing of the simulation model and enhancing the reliability and availability.
