Analysis of Methods for Reconstructing Periodically Missed SAR Data Acquired Close to Nyquist [PDF]

, 2012
The cooperative nature of the TanDEM-X mission bistatic operation allows the periodically exchange of information between transmitter and receiver over the SAR acquisition.

Quantifying the Surface Deformation of Pingos on the Alaskan North Slope Using Interferometric Synthetic Aperture Radar (InSAR)

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Pingos are large mounds with cores formed of intrusive ice that form in periglacial landscapes. These ice structures can form in regions of discontinuous permafrost, commonly as hydraulic or open‐system pingos, or in locations of continuous permafrost, commonly as hydrostatic or closed‐system pingos.

An investigation of bistatic calibration objects [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2005
Several popular metallic bistatic calibration objects are investigated, including a sphere, long and short cylinders, dihedral, trihedral, circular disk and wire mesh. Comparisons are made between the advantages and disadvantages of various objects for calibration.

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.

GPU-Accelerated Signal Processing for Passive Bistatic Radar

Remote Sensing, 2023
Passive bistatic radar is a novel radar technology that passively detects targets without actively emitting signals. Since passive bistatic radar entails larger data volumes and computations compared to traditional active radiation radar, the development

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 ...

First steps to bistatic focusing [PDF]

Proceedings. 2005 IEEE International Geoscience and Remote Sensing Symposium, 2005. IGARSS '05., 2005
Although this work is a bit theoretical and contains lots of derivations, it leads to very explicit practical results in bistatic focusing. Our approach is based on Loffelds bistatic formula describing the point targets reference spectrum for arbitrary bistatic configuration.

Non-nominal Experimental Bistatic SAR Acquisitions with TanDEM-X [PDF]

, 2012
TanDEM-X is a high-resolution interferometric mission with the main goal of providing a global and unprecedentedly accurate digital elevation model (DEM) of the Earth surface by means of single-pass X-band SAR interferometry.

An Anti-2D Deceptive Jamming Method for Bistatic SAR Based on Jammer Localization

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Synthetic aperture radar (SAR) is an essential instrument for Earth observation but is vulnerable to intentional electromagnetic jamming during imaging. Two-dimensional (2-D) deceptive jamming can introduce highly realistic false targets into SAR images,

The Calculation and Analysis of the Bistatic Quantum Radar Cross Section for the Typical 2-D Plate

IEEE Photonics Journal, 2018
The quantum radar cross section (QRCS) describes how much return one gets when illuminating an object with a handful of photons. However, the previous studies mainly focused on the monostatic scattering of quantum radar.
