Abstract

Several methods were introduced as a technique to detect underwater objects such as submarines. Acoustic methods were generally exploited for underwater objects detection. However, they are prone to be disturbed by acoustically noisy marine conditions. To solve this problem, a new method adopting the geophysical DC resistivity method is introduced. Detection feasibility of underwater objects using this method was verified through numerical modeling and physical scale modeling. When we use a detection line, a peak point of responses indicates an object position along a detection line, however, the position along the perpendicular direction is not verified. However, fast localization of the target object is required since the final goal is real-time tracking of underwater object. In this study, a localization method for moving underwater objects is introduced using two detection lines and localization algorithm is developed with response library. A feasibility of detection and localization using the algorithm is confirmed through the experiments using physical scale modeling data.
