摘要：

激光干扰是抑制红外成像系统现场性能的有效手段,为实现对激光干扰下红外成像系统性能预测,文中以激光干扰红外成像探测器的作用机理为基础,通过对红外成像系统吸收的激光能量与对比度增强之间的关系进行分析,得到干扰激光的能量与对比度增强之间的关系,进而修正红外成像系统的对比度阈值函数;并结合NVThermIP性能模型实现激光干扰对系统性能的预测,给出了仿真结果,为红外成像系统的性能预测评估和理论模型的继续完善提供依据。

Abstract:

More and more counter-measures and equipments are used to disturb the normal working of imaging system,laser interference is one of the most common and effective counter-measures,the effects of laser interference on performance prediction were hardly analyzed.Therefore,the relationship between laser energy absorbed by infrared imaging system and target contrast enhancement is analyzed on the basis of NVThermIP performance prediction model and the quantitative relation between laser energy and contrast enhancement is got,then contrast threshold function of the infrared imaging system is modified.The effects of laser interference on capability of performance prediction is compared and analyzed by NVThermIP model.The results of this research could provide the basis for performance prediction appraisal and theoretical model of infrared imaging system.

Key words: infrared imaging system;NVThermIP model;performance prediction;laser interference
