Study on the Application of Acoustic Signal Processing in Deriving the Wind Parameters

Abstract

In this research, Survey on Sound waves or acoustic waves are often utilized to study the atmospheric parameters within lowest levels of the atmosphere close to the earth’s surface due to their dependency on variations in pressure and density. Specially to study the very rapid atmospheric phenomena such as turbulence, gusts etc., acoustic waves play a vital role. This knowledge is practically used in the models for rocket launch purposes. Applications of Radar like Radio Acoustic Sounding System and Wind Profiler based duct detection techniques are explained in detail and developed by various researchers. Wind profiler and RASS, LIDAR, GPS based duct detection techniques also explained. During the survey on methods for   duct detection, many parameters like modified refractivity, atmospheric refractive index, and gradient are calculated using virtual temperature, spectral width, and the atmospheric refractive index structure constant in most of the methods. The results obtained by the researcher explained in a detailed manner in this research.
