Abstract :
A satellite mission using reflected signals from GPS satellites to remotely sense ocean wind speed/direction and soil moisture has been proposed. It relies on the measurements of forward scattered GPS waveforms which are sensitive to surface roughness and dielectric constant. By analyzing the distribution of the reflected signal in delay and Doppler, one can determine the surface characteristics. The proposed OWLS´ satellite will host a set of nadir pointed antennas and a modified GPS receiver for making these measurements
