摘要：

The importance of an improved calibration scheme for the derivation of the normalized radar cross-section coefficient sigma(0) for distributed targets using ERS-1 SAR imagery is assessed. The improved calibration scheme includes corrections relating to the saturation of the on-board Analogue to Digital Convertor (ADC) and to variations in the replica pulse power. The significance and effectiveness of the additional corrections is demonstrated by comparing the range variation of sigma(0) from 10 ERS-1.SAR.PRI images of the English Channel with that predicted by the CMOD4 scatterometer wind model. Close agreement is found at all range positions, provided the additional corrections are applied.
