摘　　要：　红外光电探测设备作用距离的大小除与设备本身的性能有关外,还制约于环境温度、相对湿度、能见度距离以及目标特性等诸多因素的影响。判定红外光电设备作用距离是否合格是目前靶场试验中突出的问题,因为考核现场很难造就标准环境(规定环境)和使用真实目标。本文利用传统的作用距离计算公式对红外光电探测设备作用距离进行计算,并对大量试验数据进行统计,对真实目标光学辐射特性进行实际测量,使计算公式的主要参数得到量化。根据红外光电设备在标准条件下所规定的作用距离要求,计算在现场试验条件下应达到的作用距离,即等效距离,以此判定红外光电设备在实际试验中所获得的实测作用距离是否满足规定要求。The effective ranging of IR photodetection equipments, in addition to the relation with the performance of the equipment itself, is restricted by ambient temperature, relative humidity, visibility ratio and target characteristics etc. To decide whether the effective ranging of IR photodetection equipments is up to standard is now a striking problem in the test-range testing,because the standard conditions are hard to be established in a test range and any real target can be hardly used under test. In this paper, the effective ranging of IR photodetection equipments is calculated by using the traditional formulas calculating the effective ranging, by counting a great number of testing data and by taking an actual measurement for the optical radiation characteristic of some real objects. The important parameters in the computation formulas are quantized. According to the requirement of the defined effective ranging at the standard condition,the effective ranging which should be within reach in the condition of the field test( i.e. the equivalent ranging) is calculated.And with this, it can be decided whether the effective ranging obtained in the actual measurement during the real testing may meet the defined requirement.
