Joint doppler and polarization characterization of moving targets.

In through-the-wall imaging radar systems, the synthesized images may not provide sufficient range and cross-range resolution for visual classification and identification of the targets. Target movement and target Doppler characteristics can be used to combat resolution limitation and improve object discrimination. However, slowly moving targets and targets moving perpendicular to the incident waves render target motion ineffective in high-resolution imaging. In this paper, we utilize the target polarization properties and introduce the time-varying polarization signature estimation based on polarization time-frequency distribution.
