Principle Analysis for Roll Attitude Measurement of Spinning Projectile Using Magnetic Resistance Sensor
摘要
Abstract
Aiming at the roll attitude measurement problem of spinning projectile by using Magnetic Resistance Sensor（MRS）,the concepts of MRS roll angle and MRS Roll Angle Rate（RAR） were presented.The corresponding equations were given.The equation about RAR of projectile and MRS RAR were given through theoretical derivation.The result shows that the measurement error between projectile RAR and MRS RAR is influenced by pitch attitude,yaw attitude and fire direction of projectile.Numerical calculation shows that the geomagnetic measurement method of projectile RAR is feasible under certain conditions,however,the precise measurement of roll angle is difficult to guarantee in application of engineering practice.关键词
