超视距空空导弹数据链系统的故障模式分析

Fault Mode Analysis of BVR Airborne Missile Data Link System

进行超视距攻击,必须采用中段惯性制导和末段主动制导相结合的复合制导体制。为了提高末段制导导引头的截获概率,需用数据链系统将载机雷达测得的目标数据送给导弹,对导弹的中段惯性制导进行修正。本文简要介绍了数据链系统的功能和原理,建立了数据链系统的故障树,并对数据链系统出现的故障模式进行了分析。

In BVR attack, the compound guidance system with inertial guidance in the middle stage and active guidance in the terminal stage must be adopted. In order to increase the acquisition possibility of the seeker in the terminal stage, target data from the plane should be sent to the missile by means of data link to correct middle stage inertial guidance. This paper briefly introduced the function and principle of data link system and built its fault tree, and it analyzed the fault mode appeared on data link system.
