摘要
大气折射率的变化影响红外和雷达波的传输,红外波段和微波波段受大气环境参量的影响不同。本文对大气环境下的光波段和雷达波段传输的折射率做了理论计算和仿真分析,结果表明,近红外与红外波段各种光波长的折射率随环境参量的变化规律基本一致。与雷达波段相比,雷达波段折射率变化对温度变化更敏感,且在标准大气条件下微波波段折射率随高度下降更快。
The transmission of infrared and radar wave is influenced by the atmosphere refractive index,the refractive index is influenced by atmosphere circumstance variance,and the effects of infrared and microwave band are quite different.In this paper,the atmosphere refractive index of optical and microwave band wavelengths under different circumstance are calculated and simulated.It is found that,comparing the different wavelengths,near infrared band and the infrared band nearly have the same rule under the same circumstance.The microwave band is more sensitive to the atmosphere temperature,and under the standard atmosphere,the atmosphere of microwave band descend faster than the infrared band.
