红外成像导引头为红外成像系统的具体应用。首先分析了红外成像系统针对不同应用需求而衍生出来的几个表征灵敏度的物理量。根据红外成像导引头的实际考核要求,概述了对红外成像导引头进行战术技术指标测量时引入的灵敏度定义。提出了一种红外成像导引头灵敏度现场校准的方法,根据此方法,分别设计了两种不同结构的现场用红外成像导引头灵敏度现场校准装置,给出了设计结果,并对这两种方案的性能进行了比较。结合外场测试数据和实验室测试数据,最终目的是要建立一个红外成像导引头灵敏度测量的行业技术规范。
Infrared imaging seeker infrared imaging system for specific applications. First of all, we analyzed several physical quantities that characterize the sensitivity derived from the different application requirements of infrared imaging system. According to the actual requirements of infrared imaging seeker, the definition of sensitivity introduced in tactical index measurement of infrared imaging seeker is summarized. A method of on-site sensitivity calibration of infrared imaging seeker is proposed. According to this method, two kinds of on-site sensitivity calibration devices for infrared seeker with different structures are designed respectively, and the design results are given. The performance of the scheme was compared. Combined with field test data and laboratory test data, the ultimate goal is to establish an infrared imaging seeker sensitivity measurement industry technical specifications.
