摘要：

红外搜索跟踪系统(IRST)是一种光电成像探测设备,广泛应用于机载平台.介绍了一种适用于实验室内评估IRST目标探测距离指标的工程实践方法:将考核条件转换为目标辐射照度,利用灵敏度测量系统精确模拟目标辐射出射度,将IRST探测距离的评估有效转换为目标探测灵敏度的测量.在实验室内对多款IRST产品在相同条件下完成测量,通过类比分析完成了目标探测距离的评估,试验方法简便又高效.%Infrared Search and Track (IRST) system is an optical imaging detection equipment used widely onboard the aircrafts.A method for evaluating the detection distance of IRST system is presented here,which is adaptive for use in the lab.Taking the target irradiance as the index,and by using a measurement system to accurately simulate the target irradiance,the evaluation of IRST detecting distance is transformed into the measurement of target detection sensitivity.We made test to multiple IRST products in the lab under the same conditions,and carried out the evaluation to the detecting distance through analogy analysis.The result shows that the method is simple and efficient.
