不同地面背景下目标与背景红外辐射对比特性

目标与背景的红外辐射对比特性研究对于红外制导和红外隐身课题都具有十分重要的意义，在此对不同地面背景下的目标车辆与背景红外辐射对比特性进行研究。先引用了目标红外辐射特性的计算公式，再分析主要水泥地面和土壤地面两种不同背景不同的辐射求解方法。最后通过仿真实验，总结出随着温度上升不同地面背景下目标车辆与背景红外辐射对比特性的变化，得到水泥地面和土壤地面中，不同发射率目标隐身需要达到的温度，为今后的目标隐身提供了数据支持。

Infrared radiation characteristics contrast between target and background on different grounds

The comparison research of infrared radiation characteristics of target and background was important for the infrared-guided and infrared stealth topics. The infrared radiation characteristics contrast between target and background on different grounds was researched in this paper. Firstly, the formula of infrared radiation characteristic of target was analyzed, then the different algorithm with different background-soil and cement was obtained. After the experiment, the transformation about the vehicle and background in different grounds was got by the temperature increase. Meanwhile, the achieved temperature of target with different emissivity in soil ground and cement ground were educed. The results also can provid the data support to target stealth in future.
