This technology relates to a magnetic field-based object localization system and method using an underwater sensor network. Specifically, it is a technology for estimating the position of moving objects using an underwater magnetic field sensor network.
Conventional localization technologies in underwater environments, such as ToA and fingerprinting, have limitations that require more accurate localization methods. This technology proposes a system for estimating the position of an object using an underwater magnetic field sensor network, and a configuration that includes a method for determining the object's entry into the sensor network.
Accordingly, this technology can improve the accuracy of localization in underwater environments by using the extracted induced magnetic field to determine an object's entry into the sensor network. It has practical value in the shipbuilding and marine, environmental, ecosystem, and electronic device sectors.
