ASAR

The Advanced Synthetic Aperature Radar (ASAR) on the European Space Agency (ESA) ENVISAT spacecraft (launched March 1, 2002). is a high resolution, all-weather imaging SAR that will provide data on ocean waves, surface topography, land surface properaties, snow and ice extent, and sea-ice processes. The ASAR operates in three modes: image mode, wide swath mode and wave mode. The imaging mode collects data in C-band (5.3 GHz) with a bandwidth of 15.55 MHz at 30 meter resolution and a swath width of 100 km. The Wide Swath Mode uses the ScanSAR technique and provides a resolution of 100 meters and a swath of 400 km. The Wave Mode also operates at 5.3 GHz with a resolution of 30 meters in 5 x 5 km swaths for imaging of ocean surface to determine ocean wave features. The ASAR C-band radar operates in either horizontal (H) or vertical (V) polarization.
