Efficient Time-Domain Focussing for General Bistatic SAR Configurations: Bistatic Fast Factorised Backprojection [PDF]

, 2010
Due to the lack of an appropriate symmetry in the acquisition geometry, generalised bistatic SAR cannot benefit from the two main properties of low-to-moderate resolution monostatic SAR: azimuth-invariance and topography-insensitivity.

Clutter Suppression Performance Analysis of Spaceborne Bistatic Radar Systems Based on a Semiempirical Bistatic Clutter Scattering Coefficient Model

Leida xuebao
Conventional spaceborne monostatic radar systems incur huge engineering costs to achieve small moving-target detection and low anti-interference ability.

Fast geolocation solution for bistatic interferometric synthetic aperture radar configuration of inclined geosynchronous transmitter with low earth orbit receivers

IET Radar, Sonar & Navigation, 2023
Spaceborne interferometric synthetic aperture radar (InSAR) technology is an effective method to obtain digital elevation model (DEM) data. The bistatic InSAR configuration of the inclined‐geosynchronous (InGEO) transmitter with low earth orbit (LEO ...

Ground Penetrating Radar Observations of Subsurface Structures From the Makgadikgadi Pans (Botswana): A Terrestrial Analogue of Martian Playa Lakes

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Playa lakes are considered promising landing sites on Mars because of their strong astrobiological potential. Therefore, sediments and buried structures in terrestrial playa lakes have become the focus of numerous analogue studies. The inclusion of ground penetrating radar (GPR) in the payloads of Martian missions has opened new avenues for ...

Refining the Simulation of Mixed‐Phase Clouds Over Coastal Antarctica With a Tailored Ice Nucleating Particle Parameterization

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Climate models have substantial biases in downwelling shortwave radiation over the Southern Ocean (SO) and Antarctica, primarily due to their inability to accurately represent the frequent occurrence of low‐level mixed‐phase clouds. Building on the evaluation of the Unified Model (UM) Regional Atmosphere and Land version 3 (RAL3), this study ...

Low‐Complexity Phase–Transition‐Based VO2 Transmissive Reconfigurable Intelligent Surface for Indoor Millimeter‐Wave Communications

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
We demonstrate a VO2‐based transmissive reconfigurable intelligent surface for indoor millimeter‐wave communication. The TRIS replaces conventional PIN and varactor diodes with geometrically tailored VO2 switches, enabling transmitted phase control through phase‐transition‐based switching.

Extending Loffeld's bistatic formula for the general bistatic SAR configuration

IET Radar, Sonar & Navigation, 2010
This study derives an accurate bistatic point target reference spectrum based on a zeroth-order polynomial model. The spectrum contains only two hyperbolic square root terms that are very analogous in form to the analytical monostatic spectrum. The new formulation can be considered as an improvement of the Loffeld's bistatic formula (LBF) and allows it

Bistatic-Like Differential SAR Tomography [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2019
Motivated by prospective synthetic aperture radar (SAR) satellite missions, this paper addresses the problem of differential SAR tomography (D-TomoSAR) in urban areas using spaceborne bistatic or pursuit monostatic acquisitions. A bistatic or pursuit monostatic interferogram is not subject to significant temporal decorrelation or atmospheric phase ...

High Resolution Field Observations of Shoreward Sediment Transport Within the Wave Bottom Boundary Layer on a Sandy Beach

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract We introduce a data archive containing the first highly resolved profiles of velocity and sediment concentration within the wave bottom boundary layer (WBBL) on a natural sandy beach. Resolution of the thin WBBL was made possible by deployment of a unique “Multi‐Frequency Doppler” (MFDop) bistatic acoustic profiling instrument on an Oregon ...

New processing approach and results for bistatic TerraSAR-X/F-SAR spaceborne-airborne experiments [PDF]

, 2009
Following the success of the first bistatic spaceborne-airborne experiment between TerraSAR-X and FSAR carried out in November 2007, DLR has performed a second bistatic experiment in July 2008 with new challenging acquisitions.
