Soldier-in-the-loop target acquisition performance model of IR imaging system

"人在回路"红外成像系统目标获取性能模型在红外成像系统分析、设计和性能评估中占有重要地位。然而经过四十多年的发展,该领域的研究现状是仍未能清楚表明模型在实际应用中的界限、程度和发展的突破方向。为此,从建立模型的角度,阐述了模型的基础,指出人眼视觉信息处理机制、杂波的定量表征是影响目标获取性能模型发展的主要因素,同时对模型发展过程中遇到的问题、相关解决方法和分歧进行了介绍,进而阐述了模型的验证方法和过程,最后讨论了如何对目标获取性能模型进一步完善。

Soldier-in-the-loop target acquisition performance model plays a very important role on infrared imaging system analysis, system design and performance evaluation. With forty years development, however, the research on such subject shows us yet unclearly the limitations for the application of the model, to what extent the model can be used, and where is the breakthrough direction for the development of the model. Consequently, from the point view of building model, the basis of building the model was discussed, it was pointed out that the information processing mechanism of human eyes and the quantitative description of background clutter on the target acquisition performance were the critical factors in the development of the target acquisition model. The issues involved in the development of the model ,the means of solving problems and the branch points of the model were also introduced. Finally, the method and the process of the model validation and the issues on how to improve the target acquisition model were also discussed.
