摘要
地基红外辐射测量设备往往被用来测量高速飞行目标的动态红外辐射特性。本文研究了计算飞行目标红外辐射特性的工程化算法。首先阐述了外场红外标定的意义,指出了外场标定与室内标定的不同。给出了平行光管标定能量传递过程、外场标定试验过程、标定数据处理方法以及影响因素。然后分析了飞行面目标辐射亮度以及点目标辐射强度计算方法,提出了适用于外场数据处理的工程化算法。最后根据实际工作经验总结分析了进行外场动态飞行目标红外辐射特性计算时存在的难点。
Ground-based infrared radiation measurement equipment is often used to measure the dynamic infrared radiation characteristics of high-speed flying targets. In this study, engineering algorithms for calculating the infrared radiation characteristics of flying targets is studied. First, the significance of infrared calibration in an outfield is expounded and the difference between indoor and outfield calibration is pointed out. The energy transfer process, outfield calibration test process, data processing method, and related influencing factors are given. Then, the methods of calculating brightness of the surface target and the radiation intensity of the point target are analyzed, and an engineering algorithm suitable for outfield data is proposed. Finally, the difficulties in calculating infrared radiation characteristics of outfield dynamic flying targets are summarized and analyzed based on practical work experience.
