摘　　要：静态性能模型对于热成像系统的评价是非常重要的。作为静态性能的一个重要参数,MRTD对系统性能的评价具有重要的意义,它的准确计算对系统视距估算影响较大。介绍了MRTD的一般模型,并编制了Matlab程序进行计算,这些计算结果有助于系统作用距离的估算。The static performance models are very important in evaluating thermal imaging systems. MTRD is an essential parameter in the evaluation standard and is also a useful tool to calculate the visual range. In this paper. MRTD is presented and calculated with MATLAB programs. These results are in concordance with the test results which other authors have obtained and helpful to evaluate the visual range of thermal imaging system.
