THE PROJECTILE ANGLE MOTION PATTERN ANALYSIS BASED ON PROJECTILE-BORNE GEOMAGNETIC SENSOR TEST

摘要

This article studied the application of geomagnetic sensor in projectileattitude test, by using the dynamic signal data of projectile flight acquiredfrom projectile-borne geomagnetic sensor, combined with projectile attitudemotion model, created a method of measuring the projectile-bornegeomagnetic signal and acquired the angle motion parameters of projectilein whole trajectory, then acquired the spin angular velocity attenuate law ofthe projectile and the whole trajectory projectile nutation angle change byanalyzing the angle motion parameters. The research shows that theprojectile angle motion parameters can be acquired from projectile-bornegeomagnetic sensor test, which being comparative analyzed with projectileangle motion characteristics, come to the analysis of the stability anddisturbance characteristics of projectile flight.
