(Chinese French Oceanographic Satellite) is a state of the art radar for several reasons. At first, SWIM is the first ever space radar concept that is mainly dedicated to the measurement of ocean waves directional spectra ([1-2]) and surface wind velocities through multi-azimuth and multi-incidence observations. Orbiting on a 500 km sun-synchronous orbit,… (More)
To assess seabed geoacoustic properties, ocean acoustic tomography (OAT) uses powerful active emissions of repetitive signals causing problems when acoustic discretion is required as in military operations. A solution to avoid this disadvantage consists in developing a new concept of OAT, called "discreet acoustic tomography", which is based on stealthy… (More)

SHORT ABSTRACT: Ocean Acoustic Tomography (OAT) uses powerful active emissions of repetitive signals causing problems when acoustic discretion is required as in military operations. In this paper, we propose to develop a new concept of OAT, called Discreet Acoustic Tomography (DAT), which is based on a stealthy acoustic signals emission. An appropriate… (More)
