Abstract :
We introduce the polarimetric time-frequency distribution (PTFD) and consider its applications to radar imaging applications for polarimetric Doppler signature estimation and source discrimination. The PTFD integrates polarization with time-frequency analysis, specifically bilinear transformations. It exploits the time-varying nature of both polarization and frequency for improved target identification, classification, and characterization.
