Frequency domain interferometry mode observations of PMSE using the EISCAT VHF radar [PDF]
Annales Geophysicae, 2000 During the summer of 1997 investigations into the nature of polar mesosphere summer echoes (PMSE) were conducted using the European incoherent scatter (EISCAT) VHF radar in Norway. The radar was operated in a frequency domain interferometry (FDI) mode

Quantum Sensor Miniaturization
, 2007 The classical bound on image resolution defined by the Rayleigh limit can be beaten by exploiting the properties of quantum mechanical entanglement. If entangled photons are used as signal states, the best possible resolution is instead given by the ...

Monitoring Bridge Vibrations via Spaceborne SAR Micro‐Doppler
Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.The advent of Synthetic Aperture Radar (SAR) imaging has presented the possibility of remote monitoring of civil infrastructure on a large scale. Although well established for observing slow and long‐term phenomena, its application to vibration‐based structural health monitoring (SHM) remains relatively unexplored in the current literature.

Acquisition of a 3 min, two-dimensional glacier velocity field with terrestrial radar interferometry
Journal of Glaciology, 2017 Outlet glaciers undergo rapid spatial and temporal changes in flow velocity during calving events. Observing such changes requires both high temporal and high spatial resolution methods, something now possible with terrestrial radar interferometry. While

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract We employ differential adjoint tomography to suppress the effects of uneven noise sources and image the upper crust S wave velocity structure of San Gabriel Basin, Chino Basin and San Bernardino Basin in the northern Los Angeles. A Sequential Subdomain Inversion strategy is implemented to address regional imbalance of sensitivity kernel ...

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract Glacial earthquakes are a class of seismic sources generated by the capsize of icebergs calved from glacier termini. Although being teleseismically observed in Greenland glaciers, seismic detection of such events in Antarctica has been elusive.
