METHOD AND ARRANGEMENT FOR NAVIGATING A ROBOT TOWARDS A MOVING TARGET

摘要

The present invention relates to an arrangement (7) in a missile and a method for guiding the said missile towards a moving target, for example an aircraft. The missile has information on its own position, velocity vector and further velocity characteristic and continuously receives information on the position and velocity vector of the target. The arrangement and the method according to the invention are characterised in that a point of interception, at which the missile is expected to strike the target, is calculated from the information on the missile and the target, and that the velocity vector of the missile is directed towards the predicted point of interception. This is continuously predicted on the basis of an assumption as to the further movement of the target and a calculation of the time to impact.
