On Theoretical Accuracy of Meteorological Targets Measurement by Radar [PDF]

Radioengineering, 2022
We draw your attention to the fact that meteorological radar does not actually measure a commonly used quantity “radar reflectivity factor,” (which is not dependent on frequency) but a different quantity called “radar reflectivity.” We present the usual ...

Xanthene based resonance Rayleigh scattering and spectrofluorimetric probes for the determination of cyclobenzaprine: Application to content uniformity test

Reviews in Analytical Chemistry, 2020
In this work, a resonance Rayleigh scattering technique and a spectrofluorimetric technique were applied to the quantification of cyclobenzaprine through two validated methods.

Polarization transfer in Rayleigh scattering of hard x-rays

New Journal of Physics, 2016
We report on the first elastic hard x-ray scattering experiment where the linear polarization characteristics of both the incident and the scattered radiation were observed. Rayleigh scattering was investigated in a relativistic regime by using a high- Z

Measurement of Temperature-Dependent Bulk Viscosities of Nitrogen, Oxygen and Air From Spontaneous Rayleigh-Brillouin Scattering

IEEE Access, 2019
In this paper, the spontaneous Rayleigh-Brillouin scattering spectra of air are simulated to study the effect of uncertainties of pressure, temperature, scattering angle and the characteristic parameter uncertainty of the Fabry-Perot interferometer on ...

Theoretical analysis of backscattering in hollow-core antiresonant fibers

APL Photonics, 2021
We present a theoretical analysis into the fundamental physical mechanisms contributing to backscattering in hollow-core antiresonant fibers. We consider Rayleigh scattering originating from the hollow regions of the fiber, which may be filled with gases,

A Fast Single-Image Dehazing Algorithm Based on Dark Channel Prior and Rayleigh Scattering

IEEE Access, 2020
The scattering of atmospheric particles significantly alters images captured under hazy weather condition. Images appear distorted, blurry and low in contrast attenuation, which extensively affects computer vision systems.

Parameter optimization for Rayleigh–Mie lidar under different dust conditions for the landing area of Martian Tianwen-1

Earth and Planetary Physics
Mars is the terrestrial planet in the solar system that is closest to the Earth. Studying the atmospheric parameters of Mars and studying the evolutionary history of the Martian environment on this basis is helpful for people to discover signs of ...

In-Flight Calibration of GF-1/WFV Visible Channels Using Rayleigh Scattering

Remote Sensing, 2017
China is planning to launch more and more optical remote-sensing satellites with high spatial resolution and multistep gains. Field calibration, the current operational method of satellite in-flight radiometric calibration, still does not have enough ...

Accuracy of radar-based precipitation measurement: An analysis of the influence of multiple scattering and non-spherical particle shape

Earth and Planetary Physics, 2018
Two assumptions are typically made when radar echo signals from precipitation are analyzed to determine the micro-physical parameters of raindrops: (1) the raindrops are assumed to be spherical; (2) multiple scattering effects are ignored.
