    The SeaSat-A Synthetic Aperture Radar System

    The SeaSat-A synthetic aperture radar imaging radar system (SAR) was the first imaging radar system used as a scientific instrument from Earth orbit. The system generated continuous radar imagery with a 100 km swath at a resolution of 25 m from an 800 km altitude orbit. The imagery is a pictorial representation of the radar backscatter of the Earth's surface in a map-like representation.
