Mining Deformation Monitoring Based on Lutan-1 Monostatic and Bistatic Data
Coal mining leads to surface subsidence, landslides, soil erosion and other problems that seriously threaten the life and property safety of residents in mining areas, and it is urgent to obtain mining subsidence information using high-frequency, high ...

Preservation of Historically and Scientifically Important Geospatial Data From Venus
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
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.

Bistatic SAR tomography: Processing and experimental results [PDF]
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.

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
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

Moving targets often appear defocused and displaced in SAR imagery, complicating detection and recognition—especially when displaced into cluttered regions, where signal‐to‐background ratio is reduced. This work presents a multistatic SAR framework that extracts moving target signatures and reconstructs focused images, providing new insights into the ...

A SIFT Algorithm for Bistatic SAR Imaging in Spaceborne Constant-offset Configuration (in English)
Focusing on the problem of the space-variance of the range cell migration term for bistatic Synthetic Aperture Radar (SAR), a Scaled Inverse Fourier Transform (SIFT) based imaging algorithm for constant-offset configuration bistatic SAR data processing ...
