Multi-Beam Detection Geometric Model Based on Genetic Algorithm

This paper develops a geometric model for multi-beam detection in seabed mapping, emphasizing the application of a genetic algorithm to optimize the layout of survey lines. Focused on addressing the challenges associated with acoustic signal projection over sloped seabeds, the study introduces novel methods for determining overlap rates, depth of seawater, and coverage width under diverse terrain conditions. It establishes a unique multi-beam space seabed coordinate system to precisely model and analyze the seafloor's geometry, facilitating the accurate mapping of marine terrains. Through the innovative use of genetic algorithms, the research optimizes the arrangement of survey lines, ensuring thorough coverage and appropriate overlap rates for effective seabed exploration. This approach not only advances the technical methodologies in marine geodesy but also broadens the scope for future applications in marine exploration and environmental monitoring, marking a significant step forward in the use of computational algorithms for enhancing the accuracy and efficiency of seabed mapping.
