A Simple RVoG Test for PolInSAR Data [PDF]

, 2015
In this paper, we present a simple algorithm for assessing the validity of the RVoG model for PolInSAR-based inversion techniques. This approach makes use of two important features characterizing a homogeneous random volume over a ground surface, i.e ...

Canopy Height and Above-Ground Biomass Retrieval in Tropical Forests Using Multi-Pass X- and C-Band Pol-InSAR Data

Remote Sensing, 2019
Globally available high-resolution information about canopy height and AGB is important for carbon accounting. The present study showed that Pol-InSAR data from TS-X and RS-2 could be used together with field inventories and high-resolution data such as ...

A Modified Three-Stage Inversion Algorithm Based on R-RVoG Model for Pol-InSAR Data

Remote Sensing, 2016
In this paper, a modified two-layer scattering model is applied to a three-stage algorithm for high-precision retrieval of forest parameters from Polarimetric Synthetic Aperture Radar Interferometry (Pol-InSAR) data. Traditional Random-Volume-over-Ground

An Automatic Mosaicking Algorithm for the Generation of a Large-Scale Forest Height Map Using Spaceborne Repeat-Pass InSAR Correlation Magnitude

Remote Sensing, 2015
This paper describes an automatic mosaicking algorithm for creating large-scale mosaic maps of forest height. In contrast to existing mosaicking approaches through using SAR backscatter power and/or InSAR phase, this paper utilizes the forest height ...

A Polarization-Power-Maximum-Based 3-D Imaging Method for Ku-Band UAV-Borne Fully Polarimetric Array InSAR

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Fully polarimetric array InSAR (Pol-array-InSAR) can obtain 3-D position information and the polarization scattering characteristics of targets. In this article, we propose a polarization analysis-based processing framework for the synthetic aperture ...
