1	Piezoelectric Sonar Sensor Design and Use for Bathymetric Map Creation by Unmanned Aerial Vehicles Morales, Connor 01 January 2017 (has links) (PDF) A genetic algorithm from literature is adapted to design piezoelectric sonar sensors using results from physics simulations to optimize for a uniform voltage response over a wide range of frequencies. The adapted genetic algorithm produces valid sensor designs, and algorithm improvements are proposed. The best case general methods for bathymetric mapping with a sonar sensor is determined by sweeping various point selection algorithms, interpolation algorithms, and algorithm parameters. A set of methods are proposed based on how many sample points are used and what error metric is preferred. Additional algorithms are suggested for future improvements. engineering thesis sonar geosciences arial vehicles Engineering
