Concerning the possibility of improving the spectroradiometric accuracy of remote sensing of the earth by means of multispectral band scanners
Abstract
Possibilities are discussed for decreasing the uncertainty of an object's emission spectrum by improving the accuracy of the calibration method and by applying a special processing method to the obtained data. It is shown that in measuring object brightness in several spectral bands, the true spectral dependence of brightness values can be determined by the method of successive approximation. The application of this technique to the remote sensing of the earth's surface by spaceborne multispectral band scanners is considered.
