Abstract

The Scanning Synthetic Aperture Radar (ScanSAR) is a powerful and widely used acquisition mode for Earth observation because of its huge imaging swath and short revisit time. These peculiarities make ScanSAR mode more advantageous of others SAR acquisition modes, in order to provide data suitable for marine applications. Data are obtained by recording backscattered signals from multiple sub-swaths in an altering manner, i.e. ScanSAR disperses the transmitted pulses to several beams by activating each beam intermittently.
