Target Locating Based On Magnetic Sensors

Using the magnetic field signal analysis and identify specific targets and actual production life in research and has some practical significance. In particular, the current magnetic sensors improve measurement accuracy, signal processing methods and computer processing power increasing, the use of magnetic field signal of the physical characteristics of a specific target, geometric characteristics, including velocity and direction, both with the feasibility.This paper discusses the use of new magnetic sensors for magnetic field signal, a certain signal analysis and calculation of the magnetic field information-based targeting. Using objective analysis of target capture and magnetic properties of the physical characteristics and motion characteristics of their own to achieve goals using magnetic properties of computer analysis to achieve specific goals and objectives of the visual analysis of location and tracking methods.Capture the current characteristics of the use of most of the goals is to use radar, sonar, image and other methods. This article discusses ways to manage in the vehicle, ship detection and localization. metal detection and other aspects of certain application. Detection of ferromagnetic objects in a variety of broad significance. Target detection with some of the existing hair, to the specific target search and tracking played a better role.This article discusses the various algorithms used to achieve target in question. When the target is only one. relatively simple mathematical model, the Newton iteration algorithm:When considering the actual situation of multiple targets or noise is more serious, consider particle swarm optimization algorithm and neural network algorithm. And the article gives some implementation of these algorithms and references.
