摘　　要：从图象信噪比及热成象系统静态性能出发，研究了景物辐射特性对热成象系统视距的影响．从目标温差、灰体景物、背景温度和高温差目标等４个方面分析并具体给出了计算机分析时的修正方法．这些已用于热成象系统性能分析软件中，对实际系统的视距估算结果与外场试验基本一致．Based upon the signal to noise ratio of the image and static performance of thermal imaging systems, the effect of scene radiant characteristics to the visual range prediction of thermal imaging systems is studied in the prisent paper. The paper gives a method of correction for the temperature difference, grey body scene, background temperature and object with high temperature difference using computer simulation. It appears that the visual range prediction for practical systems given in the present paper is in concordance with test results.
