Abstract

In this paper, we offer an overview of the frequency characteristics on the polarization orientation angle shifts induced by Man-made structures. Nowadays, it is recognized that this parameter is closely related to the target azimuth slope. The algorithm to estimate the orientation angle shifts from Polarimetric SAR data of urban area was suggested. By means of this algorithm, we compare longer wavelength L-band and shorter wavelength X-band Polarimetric SAR measurements over the same area to understand what useful information can be derived from these measurements. In addition, we examine the similarities and differences of these datasets acquired with different frequency bands. The overview is emonstrated by JAXA L-band and NICT X-band Pi-SAR data over Sendai city, Japan.
