Time-Frequency Analysis Of Natural Scene Anisotropic Scattering Behavior From Pol-In-SAR Data

摘要

In this paper, a fully polarimetric time-frequency analysis method is introduced to decompose synthesized po-larimetric and interferometric SAR images into range-frequency and azimuth-frequency domain. This 4-D representation permits to characterize the frequency response of the scene reflectivity, observed under different azimuth look-angles. A statistical analysis of polarimetric parameters permits to clearly discriminate media showing a non-stationary behavior during the SAR integration. A method is proposed to eliminate the influence of back-scattering variations in conventional polarimetric SAR data analysis.
