Polarimetric Calibration and Quality Assessment of the GF-3 Satellite Images

Sensors, 2018
The GaoFen-3 (GF-3) satellite is the first fully polarimetric synthetic aperture radar (SAR) satellite designed for civil use in China. The satellite operates in the C-band and has 12 imaging modes for various applications.

Characterization of Mass Wasting Events on Lunar Maria Using Mini‐RF Radar Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Evidence of mass wasting has been observed on the Moon since at least the Apollo era. Surface features indicative of mass wasting processes are traditionally characterized geomorphologically using visible images. In this study, we aim to better understand mass wasting features via their radar properties, which can provide insights into the ...

Interlinked Dynamics of Rice Cultivation Intensity and Ground Subsidence: Spatio‐Temporal Insights Into Water Resource Implications From Multi‐Year Spaceborne SAR Analysis

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Sustainable rice cultivation is vital to meet global food demands, particularly in regions relying on groundwater for irrigation. Over‐pumping, however, can cause significant ground subsidence, threatening both infrastructure and agricultural sustainability.

Polarimetric SAR Image Terrain Classification

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2019
In practical applications of automated terrain classification from high-resolution polarimetric synthetic aperture radar (PolSAR) imagery, different terrain types may inherently contain a high level of internal variability, as when a broadly defined class (e.g., “trees”) contains elements arising from multiple subclasses (pine, oak, and willow).

Classification of Polarimetric SAR Image Based on Support Vector Machine Using Multiple-Component Scattering Model and Texture Features

EURASIP Journal on Advances in Signal Processing, 2010
The classification of polarimetric SAR image based on Multiple-Component Scattering Model (MCSM) and Support Vector Machine (SVM) is presented in this paper. MCSM is a potential decomposition method for a general condition.

Landslide detection in mountainous forest areas using polarimetry and interferometric coherence

Earth, Planets and Space, 2020
The cloud-free, wide-swath, day-and-night observation capability of synthetic aperture radar (SAR) has an important role in rapid landslide monitoring to reduce economic and human losses.

Preservation of Historically and Scientifically Important Geospatial Data From Venus

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract A large volume of scientifically and historically important data from the early exploration of Venus is not widely available to researchers. Our work is focused on ameliorating this problem with the archival of geospatial data including radar, topography, and radiometry.

Polarimetric SAR Calibration and Processing Tool V1.0: A Tool for Polarimetric Calibration and Processing of SAR Data

2020 7th International Conference on Signal Processing and Integrated Networks (SPIN), 2020
Polarimetric SAR (PolSAR) has been widely used as an active imaging remote sensing technique to characterize manmade and natural features. The PolSAR data needs to be corrected from the polarimetric distortions to minimize the ambiguities for the accurate information retrieval of scatterers.

Ocean Oil Spill Classification with RADARSAT-2 SAR Based on an Optimized Wavelet Neural Network

Remote Sensing, 2017
Oil spill accidents from ship or oil platform cause damage to marine and coastal environment and ecosystems. To monitor such spill events from space, fully polarimetric (Pol-SAR) synthetic aperture radar (SAR) has been greatly used in improving oil spill
