Abstract

The feasibility of azimuthal Time-Frequency (TF) analysis for urban area identification using TerraSAR-X (TX) fully polarimetric data has been investigated for the first time. Space-borne sensors, unlike airborne sensors, are characterized by a very small azimuth antenna aperture, which limits the Sub-Aperture (SA) decomposition in the azimuth direction. Due to this limitation, the usefulness of SA decomposition for space-borne sensors, has still not been explored. Pixel stationarity, which generally has lower values over urban areas, has been measured for TX data. It has been found that the full doppler spectrum has to be utilized for TX to generate a meaningful stationarity pixel map from SA coherency matrices. This analysis has been performed on TX fully polarimetric data acquired in April, 2009 over a site called Wallerfing in Germany.
