Abstract

The velocity SAR (VSAR) is a conceptual SAR-based sensor system for high resolution ocean imaging. The VSAR utilizes data collected by a multi-element SAR system, to extract information not only about the radar reflectivity of the observed area, but also about the radial velocity of the scatterers in each pixel. Using this velocity information, the VSAR compensates for the velocity distortion inherent in conventional SAR and reconstructs the ocean reflectivity. We present the basic theory of the VSAR system and its performance.
