Abstract

Discusses the choice of a processing algorithm for the ENVISAT alternating polarization (AP) mode single look complex (SLC) product to be used for interferometric SAR. The chosen algorithm is a modified phase preserving range Doppler approach. The processed Doppler bandwidth is made equal to four burst bandwidths (multi-burst processing) so as to keep as much of the signal information as possible while maintaining radiometric quality. The resulting product has a modulated impulse response but contains all the necessary information required for interferometric SAR
