Study On The Geomagnetic Sensor And Application Of Missile Attitude Measurement

The research of this paper aiming at the problem occurred in attitude measure of High speed kinetic energy missile, the research on geomagnetic sensor for the missile attitude measurement was made. The following three aspects of the research were proposed:First, based on the Geomagnetism detect theory, analyzed the basic theory of geomagnetic field, the type of geomagnetic sensor and the influence of ferromagnetism material to geomagnetism detect.Second, two attitude measurement system have been designed in this paper.The first test system is designed based on the Magnetic coil for Shrapnel-pill, it has been tested by missile firing practice. Used characteristic point to calculate the Shrapnel-Pill's rotate speed and gained satisfactory testing result.The second test system is designed based on the Magnetro-resistive sensor for High Speed kinetic energy missile. it has been tested by Simulation experiment, satisfactory testing result is also gained.Finally,summed up the innovation and the weak points of the paper. The research is still need time to study.
