Abstract

The Advanced Synthetic Aperture Radar (ASAR) on-board ENVISAT is an active C-band radar that provides land cover data regardless of cloud cover and time of day/night. ASAR was designed for continuity with the image and wave modes of the ERS-1/2 AMI-SAR. It features enhanced capability in terms of coverage, range of incidence angles, polarisation, and modes of operation. This enhanced capability is provided by significant differences in the instrument design: a full active array antenna equipped with distributed transmit/receive modules which provides distinct transmit and receive beams, a digital waveform generation for pulse "chirp" generation, a block adaptive quantisation scheme, and a ScanSAR mode of operation by beam scanning in elevation.
