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 ...

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

Unambiguous signal reconstruction for GEO-LEO bistatic SAR with azimuth multichannel
The Journal of Engineering, 2019 Spaceborne bistatic multichannel synthetic aperture radar (MC-SAR) system employed inclined geosynchronous Earth orbit (GEO) transmitter and low-Earth-orbit (LEO) receiver can provide fine spatial resolution and a vast area of surveillance, which ...

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 ...

General Processing Approach for Bistatic SAR Systems: Description and Performance Analysis [PDF]
, 2010 For its intrinsic properties, bistatic SAR processing cannot be approached in the same manner monostatic SAR process- ing is approached. In general, a bistatic SAR processor is more than a powerful focussing algorithm.

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 ...

Large‐Scale Topographic Changes at Erupting Volcanoes Measured by the TanDEM‐X Digital Change Map
Earth and Space Science, Volume 12, Issue 11, November 2025.Abstract Volcanic eruptions cause large‐scale topographic changes, through the emplacement of lava flows and lava domes, the formation of craters and calderas, and thick ash and pyroclastic deposits. Here we analyze the TanDEM‐X Digital Change Map (DCM), which compares the DEM produced during 2010–2015 with satellite acquisitions collected in 2016–2022.

Fundamental aspects of netted radar performance [PDF]
, 2010 Netted radar employs several spatially distributed transmitters and receivers for information retrieval. This system topology offers many advantages over traditional monostatic and bistatic systems which use a single transmitter and a single receiver ...
