Four-component scattering model for polarimetric SAR image decomposition

Yoshio Yamaguchi, +3 more
- 25 Jul 2005 - 
TL;DR: A four-component scattering model is proposed to decompose polarimetric synthetic aperture radar (SAR) images and the covariance matrix approach is used to deal with the nonreflection symmetric scattering case.

Forest Structure Dependency of the Relation Between L-Band $sigma^0$ and Biophysical Parameters

Manabu Watanabe, +9 more
- 30 Oct 2006 - 
TL;DR: It is concluded that a possible cause of the dependency is the different characteristics of the stands rather than forest species.
Journal ArticleDOI

Observation of sea-ice thickness in the sea of Okhotsk by using dual-frequency and fully polarimetric airborne SAR (pi-SAR) data

Kazuki Nakamura, +5 more
- 24 Oct 2005 - 
TL;DR: A methodology for classifying sea-ice types by using a polarimetric decomposition technique is proposed, before comparing an estimation of the sea- ice thickness with the corresponding dual-frequency, multipolarization SAR data.
Journal ArticleDOI

Polarimetric SAR Image Analysis Using Model Fit for Urban Structures

Toshifumi Moriyama, +6 more
- 01 Mar 2005 - 
TL;DR: The proposed model fit is useful to extract polarimetric features from urban areas and the combined technique is used for feature extraction of actual X-band POLSAR data acquired by Pi-SAR.
