一、引言航空红外测温仪在实际使用中最大的问题之一是如何求改正数。原因是:(1)海洋辐射面的温度和表层(通常指零米到0.5米)的温度不一样;(2)海面並非真黑体,发射率(比辐射率)不是一,而且发射率还是一个依海况、温度、波长、观测角度而变化的一个数值。同时对天空的辐射还有反射,反射量的大小是依天空云的状况而变,(3)大气通道的吸收、
I. INTRODUCTION One of the biggest problems of aviation infrared pyrometer in actual use is how to correct the number. The reason is: (1) the temperature of the radiant surface of the ocean differs from the temperature of the surface layer (usually from 0 to 0.5 m); (2) the sea surface is not really black, the emissivity (emissivity) is not one and the emissivity is still one According to the sea conditions, temperature, wavelength, angle of observation and a value change. At the same time there is reflection on the sky’s radiation, the amount of reflection is based on the status of the sky cloud change, (3) the absorption of the atmosphere channel,
