摘要

摘要: 雷达作为典型的电子设备,在航天测控中发挥非常重要的作用。在讨论确定备件数目的基本方法基础上,分析了雷达分系统划分的基本原则,通过分系统故障概率的建模分析,在假定备件更换时间忽略不计条件下,采用泊松过程方法,推导出系统故障概率的积分表达式,据此提出了分系统平均能工作时间和平均可用度的计算方法,从而解决了雷达的分系统级别设备的备件分析问题,为航天发射场平时可用性、任务可靠性,以及备件采购等,提供了工程实用的分析和计算方法。

Abstract: A radar is a typical electronic equipment that plays an important role in the measurement and control of spaceflight missions.Based on the discussion about the number of its spare parts,the paper analyzes the basic principles of dividing its subsystems,whose failure probability was modeled.Assuming that the time for replacing the spare parts is neglected,the paper puts forward the integral expressions of the failure probability by using the poisson process.Accordingly,the paper proposes the method for calculating the mean availability and the mean working time,thus analyzing the spare parts of the radar's subsystems.This method is useful for analyzing and calculating the availability and mission reliability of the radar at the launching site and the purchase of its spare parts.
