Desenvolvimento de um array de hidrofones linearrebocado para experimento no mar

Abstract

This documentaims to describe the design and development of a linear array of hydrophones towed by a small vessel to detect acoustic signals and calculate the directionality of the submarine acoustic source through digital signal processing and algorithm implementation. The project involves the mechanical design of the prototype, the electrical connections associated with the sensors and their conditioners, the digital processing of the received signals and the implementation of specific algorithms for the geometry chosen for the array of hydrophones,and also the description of the methodology used for validation of the prototype through preliminarytestsand seaexperiment.
