摘　　要：描述了一种成像型红外系统对空间点目标探测距离的内场测试方法,介绍了以灰度描述的点目标图像的信噪比定义、空间点目标及背景的辐射特点、目标检索算法以及照度等效原理,详细描述了测试设备的搭建方法和各项参数的选取原则,并给出了相关参数的计算实例。A laboratory test method for the point target ranging in space using infrared imaging system is described. The signal-to-noise ratio （SNR） definition of point targets images described by gray level, the radiation characteristics of point targets in space and the background, target search algorithm and illumination equivalence principle are introduced. The building method of testing equipments and the choosing principle of the parameters are described in detail. And the calculation example of relative parameters is given.
