Autor: Yasuhiro Nakamura, Mitsunobu Sugimoto, Kazuo Ouchi

Publikováno v: Remote Sensing, Vol 4, Iss 8, Pp 2199-2209 (2012)

The present study introduces the four-component scattering power decomposition (4-CSPD) algorithm with rotation of covariance matrix, and presents an experimental proof of the equivalence between the 4-CSPD algorithms based on rotation of covariance

Autor: Mitsunobu Sugimoto, Armando Marino, Kazuo Ouchi, Irena Hajnsek

Publikováno v: IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing. 7:4907-4918

The surveillance of maritime areas is a major topic for security aimed at fighting issues as illegal trafficking, illegal fishing, piracy, etc. In this context, Synthetic Aperture Radar (SAR) has proven to be particularly beneficial due to its all-we

Publikováno v: Remote Sensing Letters. 4:843-852

In this study, we show the novel applications of model-based scattering power decomposition analyses in synthetic aperture radar (SAR) polarimetry for man-made target detection on the sea surface. Model-based decomposition technique is primarily used

On the eigenvalue analysis using HH-VV dual-polarization SAR data and its applications to monitoring of coastal oceans

Autor: Kazuo Ouchi, Chan-Su Yang, Mitsunobu Sugimoto

Publikováno v: SPIE Proceedings.

In the conventional SAR (Synthetic Aperture Radar) polarimetry, fully polarimetric HH-HV-VH-VV quad polarization data are used. The advantage of using quad-polarization data is more information on the scattering objects than the single- and quad-pola

Comparison of alternative parameters to dual polarimetric SAR data

Autor: Mitsunobu Sugimoto, Kazuo Ouchi

Publikováno v: SAR

The goal of this study is to examine the potential of deriving information comparable to quad-polarization synthetic aperture radar (SAR) data from dual-polarization data. Multi-polarization data have shown the potential to increase further the abili

Comparison of contrast improvement of extracted laver cultivation area using parameters derived from polarimetric SAR data

Autor: Kazuo Ouchi, Mitsunobu Sugimoto, Yasuhiro Nakamura

Publikováno v: SPIE Proceedings.

In this study, image contrast between extracted laver cultivation area and background water was extensively compared using various parameters that can be calculated by dual- and quad-polarization (fully-polarimetric) synthetic aperture radar (POLSAR)

Estimation of ocean wave height using polarization ratio of synthetic aperture radar data

Autor: Nobuaki Shiroto, Kazuo Ouchi, Mitsunobu Sugimoto

Publikováno v: IGARSS

A new technique for estimating wave height of range-traveling ocean waves by using the polarization ratio of synthetic aperture radar (SAR) data is proposed. Unlike the previous methods based on scattering models such as composite surface model [1],
