摘要
太阳是可见光波段遥感主要辐射源,太阳辐射通过地球大气二次传递至传感器时,其接收到的辐射强度与太阳辐射到达地球大气层顶的辐射强度相比,已有了很大的变化,特别是传至遥感器的地面反射太阳辐射强度受到了削弱,同时大气也是遥感图像畸变的主要原因,故在遥感测量时大气层的影响应加以考虑以消除地球大气对太阳辐射产生的重要影响.基于此,本文主要探讨了可见光波段大气对遥感图像的影响因素并对其分析.
The sun is visible bands remote sensing mainly radiation source,the solar radiation passes through Earth＇s atmosphere the second time to sensor,the solar radiation that reaches to the sensor compared to the top of the earth＇s atmosphere has changed a great deal,Especially to pass on to the remote sensing of the ground reflected the solar radiation was impaired,and the atmosphere is main cause of remote sensing images distortion,so the atmosphere should be considered to eliminate effect on the solar radiation in the earth＇s atmosphere when remote measurement.Therefore,this article mainly discusses the visible bands of remote sensing images of the factors influencing.
