地基目标光学辐射特性测量系统设计

光学特性测量技术在导弹突防领域、光学侦察和作战效果评估等领域中具有非常重要的作用。为了更好地发挥光学特性测量系统红外辐射特性测量的作用，对特性测量系统的高精度标定是非常必要的。根据研制的某型号地基目标光学特性测量系统的要求，论述了3种标定的方法，采用高精度间接扩展源法作为该系统的标定手段。从总体角度详细介绍了跟踪测量系统、黑体系统和大口径离轴平行光管的设计，使得特性测量系统具有口径为1 000 mm的跟踪测量设备、用于标定的工作温度范围在50～300 ℃的腔型黑体以及口径为1 100 mm离轴平行光管。这样地基目标光学辐射特性测量系统不仅具备了高精度的辐射标定能力，同时也具备了高精度的测量能力。

Design of ground-based optical radiation signature measurement system

The optical signature measurement technology plays an extremely important role in the fields such as missile penetration,optical reconnaissance and operational effect. In order to make better use of infrared radiation characteristics measuring in the optical signature measurement system, it is very necessary to make high-accuracy calibration of the signature measurement system. As requested in developing a certain model ground-based optical signature measurement system, three calibrating methods were discussed and high-accuracy indirect extended source methods were used for calibrating the system. From an overall point of view, the design of tracking and measuring system,blackbody system and large caliber off-axis collimators were explicitly introduced, so the signature measurement system embodied 1 000 mm tracking and measuring facilities,calibration oriented 50-300 ℃ cavity blackbodies as well as 1 100 mm off-axis collimators. Thus the ground-based optical signature measurement system is capable of high-accuracy radiation calibrating and high-accuracy measuring.
