Drone-borne Differential SAR Interferometry [PDF]

Remote Sensing, 2020
Differential synthetic aperture radar interferometry (DInSAR) has been widely applied since the pioneering space-borne experiment in 1989, and subsequently with the launch of the ERS-1 program in 1992. The DInSAR technique is well assessed in the case of

Monitoring mining-induced subsidence by integrating differential radar interferometry and persistent scatterer techniques

European Journal of Remote Sensing, 2021
Surface subsidence is a dominant component of the displacement vector triggered by underground mining. Over the last few decades, Differential Interferometry Synthetic Aperture Radar (DInSAR) has been used to efficiently monitor this phenomenon with ...

Aspherical Surface Wavefront Testing Based on Multi-Directional Orthogonal Lateral Shearing Interferometry [PDF]

Sensors
To overcome the limitations of phase sampling points in testing aspherical surface wavefronts using traditional interferometers, we propose a high-spatial-resolution method based on multi-directional orthogonal lateral shearing interferometry.

Using Artificial Neural Networks to Couple Satellite C-Band Synthetic Aperture Radar Interferometry and Alpine3D Numerical Model for the Estimation of Snow Cover Extent, Height, and Density

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
This work presents a new approach for the estimation of snow extent, height, and density in complex orography regions, which combines differential interferometric synthetic-aperture-radar (DInSAR) data and snowpack numerical model data through artificial

Differential interferometry imaging [PDF]

Symposium - International Astronomical Union, 1996
Differential Interferometry (DI) combines high spectral and high spatial resolution. On non resolved objects, it yields the angular variation of the source photocenter as a function of wavelength which has been shown theoretically and experimentally to complement very usefully both interferometric and spectroscopic data in a large number of ...

Nonlinear quantum gates for a Bose-Einstein condensate

Physical Review Research, 2022
Quantum interferometry and quantum information processing have been proposed for Bose-Einstein condensates (BECs), but BECs are described in complicated ways such as using quantum field theory or using a nonlinear differential equation. Nonlinear quantum

Radar Analysis Approach to Assess the Status of Hydromorphotectonic Changes in Central Iran(Yazd Ardakan Plain) [PDF]

مخاطرات محیط طبیعی, 2020
The phenomenon of the subsidence of the Earth is called the downward movement of the Earth's surface, which is not easily identifiable and quantifiable due to its slow evolution.

DinSAR coseismic deformation measurements of the Mw 8.3 Illapel earthquake (Chile)

Journal of Geodetic Science, 2023
The beginning of radars goes back to the 1930s where its main boost was related to the second world war. Nowadays, the techniques associated with radars are focused around a vast variety of civil, geodetic, and military applications.
