Computer simulations were used to estimate MFP performance for an underwater source in different ambient noise fields and for different array configurations. Best MFP performance was obtained in a thermal ice cracking noise field and poorest performance in a fishing boat noise field. For arrays with fewer than 40 sensors in a surface noise field, best localization was obtained with a vertical array geometry. With more than 40 sensors, billboard arrays (composed of multiple vertical line arrays) outperformed horizontal line arrays which in turn outperformed vertical line arrays ER -
