Abstract

As SAR data have much different characteristics in their geometry and radiometry compared with those of optical sensor data, it is necessary to develop a geometric and radiometric correction method of SAR data in order to use SAR data combined with other optical sensor and a map. The author developed a secondary geometric and radiometric correction method which is applicable to SAR level 2.1 standard product. The geometric correction was performed based on a foreshortening simulation applied to a reference optical sensor image. As the radiometric correction, the influence of incidence angle on radar cross section (RCS) was considered to rectify back scatter intensity after the geometric correction. The experimental studies using JERS-1 and ERS-1 SAR data showed that the correction methods resulted in fairly precise geometric correction and reasonable radiometric improvement for JERS-1/SAR data, although there remained slightly bigger error in the geometric correction and insufficiency in the radiometric improvement for ERS-1/SAR data.
