Speed Measurement and Positioning System for Plane Based on Magnetic Anomaly Detection
摘要
Abstract
In order to quickly get speed,location and other information for plane during the flight in a larger detection area,a system for detecting the speed and position of the plane was designed by calculating magnetic field strength. Mathematical model inversion of plane speed was established by calculating the induced magnetic field strength. The magnetic field strength expression of the detection system was derived. The magnetic field intensity function was simulated with detection distance and angular frequency. The impact was greater from detection distance, and the impact was smaller from the angular frequency. The magnitude of intensity of the induced magnetic field was basically in line with detection limit requirements of magnetic detectors. By the method of scaled down physical did from situation in the simulation experiments,metal rods instead of the plane,and constant magnetic field source instead of the geomagnetic field. From the tested different speeds of rods,analysis and calculation of the three magnetic field intensity detector were made. Velocity, position, and other information for target can be available, and it proves feasibility of the system.关键词
