　　从普朗克辐射定律出发，充分考虑了点目标的弥散现象、噪声以及探测器的盲元，获得了包含小目标的双波段红外仿真图像。结合红外辐射基本原理，讨论分析了基于双波段红外识别小目标的有效特征，得出目标在中波段和长波段的红外辐照度比值以及目标红外辐照度与探测距离间的关系，可以为小目标识别提供可靠的性能参数。

The dual-band IR detectors can receive the radiant energy of the target in the two bands. Based on Plank’s radiation law, and taking into full consideration to the point target dispersion phenomenon, noise and bad pixel, we get the dual-band infrared simulation image which contains small targets. Finally, combining with the basic principles of infrared radiation, we discuss the effective features to identify small targets based on the infrared dual-band. At last, we get the conclusion about the ratio of the radiation between the medium-wave and long-wave, and the relationship between radiation illumination and detection range, which can provide effective parameters of small target recognition.
