A Research on the Application of MTI in Motion Parameters Measurement on Human-rifle System

TL;DRAbstract

This paper mainly focus on the principles and methods for measurement used in MTI (Motion Track Instrument) in an effort to study the feasibility of the inclusion of MTI in parameters measurement on human-rifle system. Focused on the fixation of MTI on the rifle and the motion features of human-rifle system during automatic firing, an analysis of the coordinate is carried out, based on which the combinational attitude algorithm of gyroscope, accelerometer and magnetometer are discussed. Through MTI, motion information on the angular velocity and the angular displacement at the muzzle of a three-shot burst rifle is collected. A comprehensive analysis on the muzzle response in pitching (up and down direction) and yawing (left and right direction) is then introduced. The findings show that the data acquired through MTI can precisely indicate the actual motion of human-rifle system, revealing that MTI is sufficient in measuring motion features of human-rifle system during automatic firing.
