Polarization-Based Radar Detection in Sea Clutter.

摘要

The goal of the proposed research is to characterize and model polarization-related behaviors of sea clutter and to use these models to develop and evaluate methods for radar detection/characterization of a target on the surface of the sea. The specific propagation phenomenology that is to be exploited in this new form of detection is termed polarization mode dispersion (PMD), which is characterized by a spread in the received signal polarization state versus the signal frequency components in the radar returns. PMD is traditionally not analyzed in radar returns, but the hypothesis is that knowledge of the PMD in the returns (which is embedded via distributed clutter and target reflections) contains new forms of information.
