摘要
为了解决红外系统低背景探测性能的测试与评估问题,需要建立一套能够模拟低背景探测环境的红外冷舱测试系统。首先,介绍了国外低背景红外冷舱测试系统的发展概况;重点梳理了美国空军实验室的真空冷舱系统(KVACC)的研制历程,并介绍了KVACC的舱体、冷却系统、真空保持系统、低温准直光学系统、低温目标源及场景投影系统、低温标定系统、超洁净无尘试验室及监控系统等七大主要组成部分及各部分的功能,总结了冷舱系统研制的关键技术;分析了KVACC冷舱系统的发展途径及设计特点,并对我国冷舱技术的发展提出了建议。
In order to test and evaluate the performance of the infrared system in low-background, a cryo-chamber system is needed for simulating the low-background environment. First, the general situation of the cryo-chamber technologies abroad is presented. Then, the development of the Kinetic Kill Vehicle Hardware-in-the-Loop Vacuum Cold Chamber （KVACC） and the functions of each part are introduced, including the chambers, the cooling system, the vacuum system, the cryogenic optical system, the cryogenic radiometer system, the clean room environment and the monitoring system. The key technologies of the cryo-chamber system are summarized, including the cryogenic optical technology, the cryogenic electromechanical technology and the cryogenic resistor array technology. In the end, the development and design characteristics of KVACC are summarized, and a suggestion to the development of the cryo-chamber technologies at home is put forward.
