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 ...

Bistatic SAR Target Recognition Using Transferred Monostatic Knowledge and Cross-Domain Feature Fusion

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Bistatic synthetic aperture radar (SAR) systems offer advantages for target recognition but suffer from severe data scarcity, particularly for maritime targets, which hinders the development of data-driven deep learning methods.

Feasibility, Design, and Deployment Requirements of TCR for Bistatic SAR Radiometric Calibration

Remote Sensing, 2018
The trihedral corner reflector (TCR) is widely used as the calibration device in monostatic synthetic aperture radar (SAR) calibration, and the performance of the TCR in radiometric calibration has been studied and verified in depth.

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.

Monitoring Flood Inundation Dynamics From Space

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract With the increasing intensity and frequency of flood events worldwide, the need for accurate and timely inundation mapping has never been more critical. Large‐scale flood extent estimations are vital for coordinating effective disaster response, facilitating recovery, and building future resilience.

A Box Gradient‐Based Anisotropic Diffusion Framework for Polarimetric SAR Despeckling

Electronics Letters, Volume 62, Issue 1, January/December 2026.
This paper proposes a novel anisotropic diffusion framework for PolSAR despeckling, driven by a newly defined complex‐domain Box gradient. The method adaptively suppresses speckle while preserving structural and point‐target details, and experiments on real AIRSAR data confirm superior performance over existing filters.

A Semi‐Analytical Gaussian Beam Summation Method to Compute the RCS of Dielectric and Dielectric‐Coated Targets in Mono or Bi‐Static Configurations

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
In this article, we provide a Gaussian beam‐based method to compute the RCS of dielectric and dielectric‐coated targets in both the monostatic and bistatic cases. ABSTRACT This study proposes to extend and refine the methodology of Gaussian beam summation (GBS) for computing the radar cross section (RCS) of dielectric targets in both monostatic and ...

Generalized PFA for Air-Missile Borne Bistatic Forward-Looking Beam-Steering SAR With Accelerations

IEEE Access, 2018
For air-missile borne bistatic forward-looking beam-steering synthetic aperture radar (BFLBS-SAR), the receiver platform moves along a curve track due to the existence of accelerations.
