摘　　要：热像仪作为红外武器系统的重要组成部分,其可靠性评估越来越重要。本文通过利用可靠性预计值作为先验信息,可靠性摸底试验数据作为后验信息,开展基于先验信息的热像仪可靠性评估研究。结果表明,基于先验信息的热像仪可靠性评估方法合理可行,将会降低经典统计法对现场试验样本容量的依赖程度,减少现场样本容量,从而节省各种资源的投入。Reliability estimation of a thermal imager is becoming increasingly important in infrared weapon systems.The reliability estimation of a thermal imager based on prior information is studied using reliability expectation values and exploring experimental data as the prior information and a posteriori information,respectively,to evaluate the reliability of the thermal imager during development.The findings indicate that the method for estimating thermal imager reliability using prior information is both reasonable and feasible.This approach lessens the dependence on large field test sample sizes as typically required by classical statistics,thereby reducing resource costs through smaller field sample sizes.
