GPU-Accelerated Signal Processing for Passive Bistatic Radar
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

A Versatile Processing Chain for Experimental TanDEM-X Product Evaluation [PDF]
TanDEM-X is a high-resolution interferometric mission with the main goal of providing a global digital elevation model (DEM) of the Earth surface by means of single-pass X-band SAR interferometry.

Weak localization of light by cold atoms: the impact of quantum internal structure [PDF]
Since the work of Anderson on localization, interference effects for the propagation of a wave in the presence of disorder have been extensively studied, as exemplified in coherent backscattering (CBS) of light.

Multiband Switchable Microwave Absorbing Metamaterials Based on Reconfigurable Kirigami–Origami
A reconfigurable metamaterial featuring tunable microwave‐absorbing and load‐bearing performance is proposed. Stretchable kirigami and bistable origami configurations are integrated as actuating components, and the synergistic deformation mechanisms are systematically analyzed.

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

Back and Forward Bistatic Interferometry [PDF]
This paper characterizes the interferometric phase for a fixedreceiver bistatic SAR system. Also, the expressions for the interferometric phase and image resolution cell are summarized. It will be distinguished between two particular acquisition geometries : back-scattering and forward-scattering.

Fast direction finding for bistatic EMVS-MIMO radar without pairing
In this Communication, we revisit the parameter estimation problem in a bistatic multiple-input multiple-output (MIMO) radar system with electromagnetic vector sensors (EMVS), and a modified algorithm is suggested.
