Abstract :
Presents the project “VAGSAT” which is one of the candidates selected for a future french small satellite mission. Its aim is to provide on a global scale over the ocean, the directional spectra of the waves. The proposed system is a Ku-band radar pointing towards the surface with a small incidence angle (around 10° relative to nadir), with a real aperture antenna, and scanning conically to cover the horizontal plane over 360° in azimuth. The scientific goals of the project, its concept, and the proposed instrument are presented
