Near Surface Geophysics, EarlyView.Abstract A comprehensive multi‐method geophysical strategy is used to investigate two faults in the Northern Upper Rhine Graben. Combining industrial 3D seismic data with our own 2D P‐ and S‐wave seismic, electrical resistivity tomography (ERT) and ground‐penetrating radar (GPR), we created comprehensive subsurface images of the faults. 3D seismic data

On Entanglement-Assisted Multistatic Radar Techniques
Entropy, 2022 Entanglement-based quantum sensors have much better sensitivity than corresponding classical sensors in a noisy and lossy regime. In our recent paper, we showed that the entanglement-assisted (EA) joint monostatic–bistatic quantum radar performs much ...

Characterization of Multi-Link Propagation and Bistatic Target Reflectivity for Distributed Multi-Sensor ISAC [PDF]
arXiv, 2022 Integrated sensing and communication (ISAC) qualifies mobile radio systems for detecting and localizing of passive objects by means of radar sensing. Advanced ISAC networks rely on meshed mobile radio access nodes (infrastructure and/or user equipment, resp.) establishing a distributed, multistatic MIMO radar system in which each target reveals itself ...

Laser Terminals on CubeSats: Developments for Telecommunications and Quantum Links
International Journal of Satellite Communications and Networking, Volume 43, Issue 3, Page 133-146, May/June 2025.ABSTRACT Satellite‐based laser communication is an emerging technology that is finding its way from research to industry. Compared to radio frequency (RF) systems, it has a more efficient size, weight, and power budget and, furthermore, is license free.

Bistatic Experiment Using TerraSAR-X and DLR’s new F-SAR System [PDF]
, 2008 A bistatic X-band experiment was successfully performed early November 2007. TerraSAR-X was used as transmitter and DLR’s new airborne radar system F-SAR, which was programmed to acquire data in a quasi-continuous mode to avoid echo window ...

Can GNSS reflectometry detect precipitation over oceans? [PDF]
, 2018 For the first time, a rain signature in Global Navigation Satellite System Reflectometry (GNSS‐R) observations is demonstrated. Based on the argument that the forward quasi‐specular scattering relies upon surface gravity waves with lengths larger than ...

Development of BREM Software for Bistatic Radar’s Range Estimations
Ingeniería, 2017 A radar device is considered to be bistatic when the transmitter and receiver are placed on locations separated by a distance considerably greater than the distance from the target.
