热成象系统对扩展源目标的视距估算

Visual Range Prediction for the Extended Source Target in Thermal Imaging Systems

从热成象系统静态性能出发，研究了热成象系统对扩展源目标的视距估算模型．给出了计算机分析模拟时目标形状、大气衰减、探测概率及信噪比等的处理方法，编制了计算程序．计算结果表明：模型是可行的，对系统视距的估算与实际试验结果基本一致．

Based on the static performance of thermal imaging systems , a mathematical model for the visual range prediction adaptal for extended source target is studied. This paper gives a method of treatment for the problem using computer sedation, and acomputer program has been complied. The results shows that the model given in the paper is practicable and feasible, and the visual range prediction given for the extended source target is in concordance with the test results.
