Doppler Synthetic Aperture Radar Interferometry: A Novel SAR Interferometry for Height Mapping using Ultra-Narrowband Waveforms [PDF]
, 2017 This paper introduces a new and novel radar interferometry based on Doppler synthetic aperture radar (Doppler-SAR) paradigm. Conventional SAR interferometry relies on wideband transmitted waveforms to obtain high range resolution. Topography of a surface is directly related to the range difference between two antennas configured at different positions.

SURE-Fuse WFF: A Multi-Resolution Windowed Fourier Analysis for Interferometric Phase Denoising
IEEE Access, 2019 Interferometric phase (InPhase) images, acquired by phase imaging systems, often suffer from two major degradations: 1) phase wrapping, caused by the sinusoidal 2π-periodic sensing mechanism, and 2) noise, introduced by the acquisition process or ...

Probing non-Abelian statistics with Majorana fermion interferometry in spin-orbit-coupled semiconductors [PDF]
Phys. Rev. B 84, 085109 (2011), 2010 The list of quantum mechanical systems with non-Abelian statistics has recently been expanded by including generic spin-orbit-coupled semiconductors e.g., InAs) in proximity to a s-wave superconductor. Demonstration of the anyonic statistics using Majorana fermion interferometry in this system is a necessary first step towards topological quantum ...
