ABSTRACT
While the ScanSAR is a very useful mode for Earth observation because of its wider swath, it sometimes suffers due to artifacts such as (1) scalloping, which often appears as repeating weak azimuth stripes; (2) azimuth ambiguity (i.e., a form of ghosting that appears over the adjacent uniform area when the pulse repetition frequency [PRF] is below the Doppler bandwidth); and (3) radiometric discontinuity (banding) between two adjacent scans. This chapter describes the methodology for correcting them. Several corrected sample data sets from ALOS/PALSAR are presented.
