Abstract
This work aimed to synthesize, from computer simulations, radiation patterns of linear arrays of acoustic projectors of the piston type (Tompilz). This paper also has the focus to analyze the behavior of these radiation patterns when varying some parameters and characteristics of the array and radiating elements. For the array, it was considered the influence of variations related to the number of elements and the distance between them. For the elements, it was analyzed the changes in the diagrams when the product between the radius of the projector's head and the acoustic wavenumber was varied. These parameters were chosen because of his notorious influence in the shape of radiation patterns. Also, it was investigated the influence of radiation on patterns of multipath and Doppler spread, as well as the efficiency of a LMS (Least Mean Square) filter applied in the received signal. These results find application in the design of linear arrays of projectors and the development of beamforming techniques.
