A GPS Bistatic Radar System for Ocean Altimetry

Description of a Bistatic System for Ocean Altimetry Using the GPS Signal

This paper presents the fundamental characteristics of bistatic altimetry performed using the Global Positioning System (GPS) signal scattered off the ocean surface and collected by a receiver in space. The advantage of the dense and rapid surface coverage afforded by the existing GPS constellation would enable new oceanographic applications such as eddy monitoring and the tracking of fast baro...

Bistatic Ocean Wave Remote Sensing System by GPS

On the Achievable Accuracy for Estimating the Ocean Surface Roughness using Multi-GPS Bistatic Radar

The signals from the Global Positioning System (GPS) reflected from the ocean surface have been considered for bistatic GPS remote sensing to estimate parameters including wind speed and height and roughness of the ocean surface. A variety of models, methods, and experimental campaigns have verified the level of viability and reliability of the bistatic GPS radars. In this article, we analyse t...

5-cm-Precision aircraft ocean altimetry using GPS reflections

[1] We present the first two aircraft Global Positioning System (GPS)-reflection altimetry measurements, the most precise GPS ocean-altimetry measurement, and demonstrate the altimetric precision and spatial resolution necessary to map mesoscale eddies. Our first experiment demonstrated a 14-cm precision single-satellite ocean altimetry measurement while our more recent experiment demonstrates ...

Polarimetric bistatic radar scattering behavior of the ocean surface

this paper points out the frequency dependence on the polarimetric radar scattering behavior of the ocean surface in the frequency range 1-18 GHz (Lto Ku-band). We treat this problem with a unifying scattering model named Small Slope Approximation (SSA) to evaluate the Normalized Radar Cross Section (NRCS). The calculations were made by assuming the surface-height spectrum of Elfouhaily et al f...
