The Relationship between Land Subsidence and Water Use in Yazd-Ardakan Plain Using Sentinel-1 Images [PDF]

تحقیقات کاربردی علوم جغرافیایی
In arid and semi-arid regions, groundwater is more important for humans and ecosystems than surface water. Land subsidence is caused by the pumping and uncontrolled use of groundwater in an area.

Application of Fractional Fourier Transform to Hologram Formation of a Moving Acoustic Source

Fractal and Fractional
This paper examines how the fractional Fourier transform (FrFT) can be used to form and analyze acoustic holograms produced by a moving, linear, frequency-modulated (LFM) source in a shallow water waveguide.

Interferometric Surface Analysis of a Phase-Only Spatial Light Modulator for Surface Deformation Compensation

Photonics
A spatial light modulator (SLM) is a key element in several applications, but it is subject to surface deformation due to manufacturing imperfections or environmental factors.

A Nonlocal Filter for SAR Interferometric Phase Based on Partial Siamese Network

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Filtering is a crucial step in synthetic aperture radar (SAR) interferometric phase processing. In the context of rapid development in deep learning, the interferometric phase filtering networks have demonstrated more powerful filtering capabilities than

Digitalized reduction of interferograms

, 1990
The factibility of the reduction of interferograms obtained with the fixed-gap Fabry-Perot etalon of Córdoba Observatory by using a digitalized Hilger-Watts microdensitometer is analyzed. For this purpose, radial velocities of an in-rest comparison source were calculated, following the method proposed by Courtés.
