Extended Kalman Filtering and its Application to Intelligent Missile Formation Flight Mechanics

Article Preview

Abstract:

Aimed at the needs of intelligent missile cooperative engagement mission, a relative navigation method based on INS/Vision is presented, and the relative inertial equation between leader missiles and attack ones is derived. The line of sight measurement is acquired by observing the beacons on the attack ones using the vision navigation equipment on the leader missiles. The extended Kalman filter is used to estimate the relative attitude, relative velocity and relative position by fusing the inertial navigation information and the line of sight measurement. Simulation results verify the effectiveness of the relative navigation method. Improve the estimated accuracy of missile in formation flight mechanics.
