为了能在实验室内对红外成像制导系统进行在线实物仿真，以减少大量耗时费力的外场试验，需要相应的动态红外景像模拟器，它能产生不同时间和环境条件下二维目标与背景的动态红外辐射景像。本文描述了动态红外景像模拟器的性能评价指标、多种实现方法及特点。动态红外景像模拟技术不仅适用于红外成像制导系统的在线实物仿真，还可用于热成像系统和光电对抗系统的实验室评价。 In order to be able to conduct in-line physical simulation of infrared imaging guidance system in the laboratory to reduce a large amount of time-consuming field experiments, a corresponding dynamic infrared scene simulator is needed, which can generate two-dimensional objects and backgrounds under different time and environment conditions Dynamic infrared radiation images. This article describes the dynamic infrared scene simulator performance evaluation index, a variety of methods and features. Dynamic infrared image simulation technology is not only suitable for in-line physical simulation of infrared imaging guidance system, but also for laboratory evaluation of thermal imaging system and photoelectric countermeasure system.
