Midcourse guidance for the US Army's low cost fiber optic guided missile
Abstract
A method for achieving midcourse guidance using a digital correlator and known white rocks, or positions of objects that appear in the seeker video is analyzed. A variety of filtering techniques and filter mechanizations are analyzed and the results presented. Algorithms are developed which use updates from the ensemble of white rocks or waypoints to correct the missile attitude at each waypoint and predict time or range to go to the target area. Models for the system dynamics and the measurement process were formulated and six extended Kalman filter designs were developed and tested for state estimation accuracy and efficiency. Work was also performed to improve the efficiencies of the algorithms so that the estimates are available in a timely manner for midcourse navigation and to aid the operator.
