Estimativa do estado do mar gerada pelo vento e suas correlações com as medições do ruído ambiente geradas pelo vento associada com a escala de vento Beaufort em águas rasas

Abstract

This master’s dissertation presents a technique for estimating the state of the sea through passive interactions with the ambient noise generated by the wind, associated with the Beaufort wind scale for shallow waters. This study consists of a methodology using the curves proposed by Knudsen, to associate a certain frequency band captured by a hydrophone that can assist oceanographic buoys to collect data about the state of the sea and wind speed, and can also assist submarines that need information about the state of the sea to feed data their respective combat systems. The eld experiments performed showed good correlation with the Kndsen curves for medium and high frequencies, which made it possible to generate a model considering the speci cities of the explored region.
