Small Structures, Volume 6, Issue 12, December 2025.This work presents a transparent transmissive metasurface (TTM), designed using a conditional generative adversarial network to achieve broadband electromagnetic illusions. The proposed TTM ensures high optical transparency while precisely manipulating electromagnetic waves, demonstrating effectiveness in practical applications such as camouflage ...

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.

GNSS-Based Phase Synchronization for Bistatic and Multistatic Synthetic Aperture Radar [PDF]
IEEE Transactions on Geoscience and Remote SensingThe feasibility of single-pass interferometric or multistatic synthetic aperture radar (SAR) mission concepts largely relies on the ability to achieve the matching of the carrier phase of the different radar instruments of the constellations within a few degrees.

Reviews of Geophysics, Volume 63, Issue 4, December 2025.Abstract Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, associated with ice‐crystal orientation fabric (COF), or extrinsic, associated with material heterogeneity, such as bubbles, fractures, and ...

Coherent Integration for Cooperative Bistatic Radar with Joint Time-Domain Waveform Agility
Remote SensingWaveform agility improves anti-reconnaissance and anti-jamming capability in diverse inverse synthetic aperture radar (ISAR) scenarios, but it also breaks the phase variation assumptions used for conventional coherent processing. For cooperative bistatic

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.

A Novel Strategy for Radar Imaging Based on Compressive Sensing [PDF]
, 2010 Radar data have already proven to be compressible with no significant losses for most of the applications in which it is used. In the framework of information theory, the compressibility of a signal implies that it can be decomposed onto a reduced set of

Near-Space Microwave Radar Remote Sensing: Potentials and Challenge Analysis
Remote Sensing, 2010 Near-space, defined as the region between 20 km and 100 km, offers many new capabilities that are not accessible to low earth orbit (LEO) satellites and airplanes, because it is above storm and not constrained by either the orbital mechanics of ...
