ABSTRACT:
A global positioning system (GPS) ocean scatterometer with an adaptable spatial resolution for sensing and processing GPS signals reflected from an ocean surface for wind measurements in a wide range of altitudes and wind velocities. To increase wind sensitivity at low altitudes, the GPS ocean scatterometer employs a sub-chip GPS receiver which includes, inter alia, a signal correlator and a pair of code correlators for generating a sub-chip footprint to boost system resolution. To increase wind sensitivity at high altitudes, the GPS ocean scatterometer employs a multi-chip GPS receiver which includes, inter alia, a wide-band oscillator and a multi-chip generator for generating a multi-chip footprint to boost scattered energy.
