Coherent interferometric imaging in clutter [PDF]

open access: yesGeophysics, 2006
Abstract Coherent interferometry is an array-imaging method in which we back-propagate, or migrate, crosscorrelations of the traces over appropriately chosen space-time windows rather than the traces themselves. The size of the space-time windows is critical and depends on two parameters.

An Adaptive Phase Optimization Algorithm for Distributed Scatterer Phase History Retrieval

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The multitemporal interferometric synthetic aperture radar (InSAR) technique based on distributed scatterers (DSs) has been widely applied in high-precision deformation measurements, which compensates for the drawback that the persistent scatterer InSAR ...

Enhancing Coherence Images for Coherent Change Detection: An Example on Vehicle Tracks in Airborne SAR Images

open access: yesRemote Sensing, 2021
In Synthetic Aperture Radar (SAR) interferometry, one of the most widely used measures for the quality of the interferometric phase is coherence. However, in favorable conditions coherence can also be used to detect subtle changes on the ground, which ...

Macroscopic and deterministic quantum feature generation via phase basis quantization in a cascaded interferometric system

open access: yesScientific Reports, 2021
Quantum entanglement is the quintessence of quantum information science governed by quantum superposition mostly limited to a microscopic regime. For practical applications, however, macroscopic entanglement has an essential benefit for quantum sensing ...
