摘　　要：通过分析在夜视条件下短波红外、中波红外和长波红外点目标辐射成像机理,明确了多波段红外成像的影响因素,建立了短波红外、中波红外和长波红外图像点目标的形成模型,并对模型进行分析与仿真实验,揭示了多波段红外点目标夜视成像特性差异的形成机理,比较了多波段红外点目标成像的差异,并且通过实验图像的差异特征验证了这些成像特性差异的存在性,最后得出了多波段红外点目标图像的灰度值存在差异,大气传输影响存在差异以及夜光辐射影响存在差异的结论。Through analysing the SWIR, MWIR and LWIR point targets radiation night vision imaging mechanism, multi-band infrared imaging influence factors are proposed, the formation models of point targets in SWIR, MWIR and LWIR images are set up, and these models analysed and simulated. It is revealed that the formation mechanism of multi-band infrared point targets night vision imaging characteristic differences. The differences among the multi-band infrared point targets imaging are compared, and the existence of imaging characteristics differences is verified through features differences in experiments images.At last the conclusion is drawn that there are differences among the gray value, atmospheric transmission effect and the night sky light radiation effect.
