A SAR system with an antenna divided into sub-apertures is considered for marine surveillance. Ship position and radial and along-track components of its cruising velocity are estimated in the presence of wave-induced motion, using a combination of adaptive beamforming, frequency tracking and along-track interferometry. The effectiveness of this new(More)
This paper describes a complete procedure for estimation and compensation of ship motion in SAR data. Our methodology relies on extraction and modelling of the Doppler phase history and power envelope in slow time. The model parameters have a physical interpretation under the assumption that the cruising velocity is constant and that the wobbling is a(More)
Vessels on the ocean surface move in response to propulsion forces and the dynamics of the ocean surface. A SAR measures precisely the time delay between the transmission and reception of a RADAR pulse. This paper presents a parametrization of the equations describing the movement of a vessel as it is imaged by a single channel airborne SAR. This(More)
