A Monostatic Ocean Scattering Cross Section for the Case of Surface Wave Radar Operating from a Floating Barge

An understanding of the parameters affecting the high frequency surface wave radar (HFSWR) cross sections of the ocean surface is essential to employing such formulations in remote sensing models. Available techniques to date have not explicitly included the effect of antenna motion on the ocean clutter spectra derived from HF Doppler radar data. Here, a model, which assumes the incident radiation to be a simple pulse and accounts for the fact that there may be antenna motion in the radar look direction, is presented. Simulations indicate that the motion of the antennas may give rise to additional, significant spectral content which cannot be ignored when the Doppler spectra are used for ocean parameter estimation.
