摘　　要：为了降低对红外热像仪最小可分辨温差(MRTD)检测的成本,对使用者一级的MRTD检测方法进行了研究,提出了一种基于FLIR92模型和BP神经网络的MRTD检测方法。该方法在兼顾检测精度的基础上,对检测条件和检测人员的要求大大降低,同时降低了检测成本,对降低红外热像仪的使用和维护成本具有重要意义。For reducing the cost of testing the minimum resolvable temperature difference （MRTD） of the infrared thermal imaging system, a MRTD testing-method on user-level had been researched and a method based on FLIR92 model and BP neural net work had been put forward. This method reduces the requirement of experiment conditions and testing-man and also has a sufficient testing-precision. It has a important meaning on using and maintenance of the thermal imaging system.
