Abstract

The invention relates to an underwater target tracking method based on electromagnetic field feature multi-information fusion. The method comprises the steps of arranging a plurality of magnetic fieldsensors and electric field measurement electrodes in an array mode, obtaining the three-direction coordinate position initial solution of an underwater target, a magnetic dipole moment and an electric dipole moment through the calculation of a gradient positioning algorithm, establishing a state equation and an observation equation of the underwater target based on the underwater target electromagnetic field model, and performing nonlinear state estimation of the underwater target by adopting a particle swarm filtering algorithm to realize dynamic tracking of the underwater target. The methodis suitable for the field of underwater safety alert, and is good in algorithm adaptability and high in tracking precision.

Description

technical field [0001] The invention relates to the technical field of underwater target detection, in particular to a method for locating and tracking the target in the water by utilizing the electromagnetic field characteristics of the target. Background technique [0002] In order to achieve the security of our country's bay or coastal military fortresses, important ports, and important waters, it is urgent to build an underwater detection and positioning system to realize the normalization of underwater security. [0003] Underwater, it can detect and locate through the acoustic field, electromagnetic field and optical characteristics of underwater targets, so as to realize underwater security warning. For most underwater targets, they are made of metal with a fixed magnetic field, and at the same time, they will generate an induced magnetic field under the action of the geomagnetic field, and the self-corrosion and corrosion protection systems between different metals w...
