Magnetic Sensor for Detection of Ground Vehicles Based on Microwave Spin Wave Generation in Ferrite Films
Abstract
We propose to use the magnetic signatures, formed either by the residual magnetization or by deformation of the local Earth's magnetic field by large metal masses, for distant detection of ground vehicles. Measuring this weak magnetic field would allow one to determine the position, type, and velocity of the vehicle. Wirelessly transmitting data from the net of such detectors and processing the obtained information at the central processing computer will enable one to determine the number of ground vehicles and their individual characteristics in a group. The problem of vehicle detection is of great importance for both the combat and civil applications. The usual radio and microwave frequency radar technologies, which are successfully used for the detection of flying objects, have a limited application for the solution of this problem, due to a strong noise signal created by other surface objects (like buildings and trees) and by the Earth surface itself. The proposed magnetic sensor will not be affected by the weather conditions, such as snow, fog, or rain. It can be used in urban setting.
