Linearized common curvature guidance law for homing missiles

This paper suggests a new concept for missile guidance control, called Linearized Common Curvatun Guidance Law that enhances the probability to kill a target. The proposed guidance system is composed of two switching modes; one for the midcourse guidance and the other for the terminal guidance, which is switched by a specified critical value(epsilon). The system and commands are formulated and its simulation is provided in comparison with the conventional commanded line of sight guidance algorithm. Miss distance and angle of intercept are denoted as performance indices. This new concept, common curvature guidance algorithm, revises the navigation guidance and accompanies various considerations providing a new parameter - common curvature.
