红外成像导引头灵敏度现场校准技术研究

Research on local sensitivity calibration of infrared imaging seeker

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 system was applied in infrared imaging seeker. At first, several parameters meaning sensitivity which vary with the different use were analyzed. Meeting with the practical evaluation need, the definition of sensitivity which was introduced in the process of performance test was described. A local method of infrared seeker sensitivity calibration was advanced. According to the method, a design about two local device for infrared seeker sensitivity test with different configuration was made. ...
