Sparse vegetation height estimation based on non‐local sample selection with generalised inner product

IET Radar, Sonar &Navigation, Volume 18, Issue 7, Page 1106-1115, July 2024.
The manuscript mainly investigates the sparse distributed vegetation height inversion problem. By analysing the scattering mechanisms of the sparse distributed vegetation, the authors proposed a method to select the samples to estimate PolInSAR coherence and vegetation height in non‐local areas by using the amplitude‐normalised interferometric phase ...

Polarization Impact in TanDEM-X Data Over Vertical-Oriented Vegetation: The Paddy-Rice Case Study [PDF]

, 2015
It has been recently shown that the TanDEM-X mission is capable of tracking the plant growth of rice paddies. The precision of the elevation measure depends on the physical interaction between the synthetic aperture radar (SAR) signal and the canopy.

Topographic Correction for Biomass Retrieval from P-band SAR Data in Boreal Forests [PDF]

, 2010
The influence of the ground slope on radar backscatter has been proven to be greater for lower radar frequencies due to deeper canopy penetration. In this study, multiple heading, Pband SAR data of boreal forest in Sweden was used to find a model for ...

An Improved Three-Component Decomposition Method for $\pi$/4 Mode Compact PolInSAR Using Refined Volume Scattering Models

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
In this article, an improved three-component decomposition method for $\pi /4$ compact polarimetric synthetic aperture radar Interferometry (PolInSAR) is proposed to interpret the scattering mechanisms of various terrain types.
