1) radiation contrast
辐射对比度
1.
Based on the infrared stealth mechanism,a new study orientation is put forward for the infrared camouflage coating technology with the judgment criterion of infrared stealth,in which the radiation contrast between target and background should be less than 0.
从涂料的隐身机理出发,以目标与背景的辐射对比度小于0。
2) infrared contrast
红外辐射对比度
1.
Aiming at the issue of aircraft infrared camouflage,the relationship between the infrared contrast and the operating range of an infrared system was deduced,an approximate expression for the relation between the atmospheric transmittance and operating range was obtained through exponential fitting,and a simplified method of calculating the operating range was developed.
针对飞行器的红外隐身问题,推导出红外辐射对比度与作用距离的理论关系,采用指数拟合获得大气透过率与作用距离的近似关系表达式,简化了对作用距离的计算,并通过实际算例考察了目标表面温度、目标发射率和飞行速度对红外辐射对比度及作用距离的影响。
3) specific intensity of radiation

4) radiation-convection temperature
辐射对流温度
5) relative radiation density
相对辐射密度
6) absolute radiometry
绝对辐射度学
