Title Proper : Modeling the Forward Look Sonar
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : A numerical model that simulates the operation of a Forward Look Scan Sonar (FLSS)has been developed in this thesis. The model discretizes the sonar-projected signal by aset of rays using a geometrical approach. Bending of the rays due to varying acousticwave speed is neglected. Simulated raw sonar data are generated, and used as input inthe sonar processing algorithms to generate sonar images. Using the model, the influenceof the most critical characteristics of the sonar, including phase variations among thechannels, non-homogeneous channel amplitude, and the number of bad channels, on thequality of the sonar image is determined. The results of the model are compared to real..,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
