卫星遥感数据的大气校正, 一直是遥感定量化研究的主要课题之一。由于许多参数不容易得到, 用大气辐射传输方程进行大气校正, 难以实现。本文提出了校正大气影响的裸沙土壤线方法。用 N O A A 气象卫星遥感数据在黄土高原地区进行了试验。结果表明, 在该地区用裸沙土壤线法校正大气影响, 方法简便, 精度高。经校正的同系列不同气象卫星的遥感数据可以相互比较。该方法可应用于干旱、半干旱地区卫星遥感数据的大气校正。
Atmospheric correction of satellite remote sensing data has always been one of the major topics in quantitative research of remote sensing. Since many parameters are not readily available, it is difficult to achieve atmospheric correction using the atmospheric radiation transfer equation. This paper presents a method of correcting the bare soil soil line affected by the atmosphere. Naohe meteorological satellite remote sensing data in the Loess Plateau region has been tested. The results show that the method of bare soil correction of the atmosphere with naked soil in the region, the method is simple and high precision. The corrected remote sensing data of different meteorological satellites of the same series can be compared with each other. The method can be applied to the atmospheric correction of satellite remote sensing data in arid and semi-arid areas.
