Bistatic SAR tomography: Processing and experimental results [PDF]
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010 This paper presents across-track tomography applied to a bistatic geometry with fixed receivers. This kind of geometry can overcome some of the classical monostatic tomography limitations such as temporal decorrelation and irregular baseline distribution.

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.

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 ...

Focusing Bistatic FMCW SAR Signal by Range Migration Algorithm Based on Fresnel Approximation
Sensors, 2015 Frequency modulated continuous wave (FMCW) technique has recently been employed by synthetic aperture radar (SAR) to decrease the radar cost and volume. However, the operation range is limited by the direct energy leakage from the transmitting channel to
