Angle of Arrival Distribution in an Underwater Acoustic Communication Channel With Incoherent Scattering

open access: yesIEEE Access, 2020
Angle of arrival (AoA) analysis is essential for the statistical characterization of the underwater (UW) channel where the acoustic signal propagation is confined to a restricted geometry.

Three-Dimensional Incoherent Imaging Using Spiral Rotating Point Spread Functions Created by Double-Helix Beams [Invited]

open access: yesNanoscale Research Letters, 2022
In recent years, there has been a significant transformation in the field of incoherent imaging with new possibilities of compressing three-dimensional (3D) information into a two-dimensional intensity distribution without two-beam interference (TBI ...

Hierarchical Deconvolution for Incoherent Scatter Radar Data [PDF]

open access: yesAtmospheric Measurement Techniques, 2021
Abstract. We propose a novel method for deconvolving incoherent scatter radar data to recover accurate reconstructions of backscattered powers. The problem is modelled as a hierarchical noise-perturbed deconvolution problem, where the lower hierarchy consists of an adaptive length-scale function that allows for a non-stationary prior and as such ...

Neutron incoherent scattering from KDP [PDF]

open access: yes, 1969
The incoherent, inelastic neutron cross section is derived for KH2PO4, following the model discussed by Tokunaga and Matsubara. This expression should give the dominant contribution of the proton tunneling motion to the cross section. Matsubara has given

A Consistent Approach to Incoherent Scattering of Channeling Particles [PDF]

open access: yes, 2015
The incoherent scattering of planar channeling particles is quantitatively treated using Wigner function determined in the transverse phase space. The local approach of Kitagawa and Ohtsuki is substantially developed by taking into consideration the ...

Diffraction of an electromagnetic wave on a countless number of scatterers

open access: yesВісник Харківського національногоуніверситету імені В.Н. Каразіна. Серія: Радіофізика та електроніка, 2022
Topicality. The task of finding the radar cross-section (RCS) of complex objects is of great importance. Usually, when creating radar stations, RCS is measured on real targets.

Neutron frequency windows and the protein dynamical transition [PDF]

open access: yes, 2004
Proteins undergo an apparent dynamical transition on temperature variation that has been correlated with the onset of function. The transition in the mean-square displacement, ∆r2 , that is observed using a spectrometer or computer simulation, depends on

Basal unit radar characteristics at the southern flank of Dome A, East Antarctica [PDF]

open access: yesThe Cryosphere
The basal unit near the base of the Antarctic Ice Sheet (AIS) plays a critical role in AIS dynamics and the preservation of old ice, yet its structure and origin remain poorly understood.
