光电系统对空目标探测距离评估方法研究

On method for evaluating detection distance of EO system

为估算光电系统的目标探测距离,研究了目标的红外辐射特性和在实验室内对系统灵敏度进行测试的方法。在系统设计阶段,可以利用系统设计参数估算光电系统目标探测距离;在系统样机研制完成后,可以利用系统灵敏度测试,对光电系统目标探测距离进行估算。经实际系统试飞试验表明目标探测距离评估方法是可行的。

For evaluating the detection distance of an electro - optic system, the characteristics of target infrared radiation and the test method of detection sensitivity of the system in laboratory are studied. In the phase of design, the detection distance can be calculated from the design parameter of the system. After the system is made, the detection distance can be evaluated according to test of the detection sensitivity of the system. Hight - test proved that the method is feasible for evaluating the detection distance of an electro- optic system.
