Dept. of Electrical & Electronic Engineering. Sonar -- Mathematics Transducers -- Mathematics Dissertations -- Electronic engineering Thesis (M. Ing.) -- University of Stellenbosch, 1992. At present there exists little if any published literature dealing with chirp side-scan sonar. It is suggested that chirp side-scan sonar offers range and resolution improvements over commercially available side-scan sonar. The improvement in resolution is a result of better use of the available bandwidth, while the improvement in range is due to the lengthened signal containing more energy. This text models the transmit and receive transducers with the Mason model, and investigates ways of implementing chirp in side-scan sonar successfully. The performance of the suggested design is estimated and compared with currently available systems. The chirp signal was investigated through spectral analysis, numerical analysis and simulations of the actual system. Experimental work was also done, in a tank, so as to determine the correlation of the theory with practice. On the basis of this research it can be concluded that chirp side-scan sonar is a feasible system that represents great improvements over commercially available products, in terms of range and image quality.
