A Terminal Guidance Law Based on Motion Camouflage Strategy of Air-to-Ground Missiles

Abstract EN

A guidance law for attacking ground target based on motion camouflage strategy is proposed in this paper.

According to the relative position between missile and target, the dual second-order dynamics model is derived.

The missile guidance condition is given by analyzing the characteristic of motion camouflage strategy.

Then, the terminal guidance law is derived by using the relative motion of missile and target and the guidance condition.

In the process of derivation, the three-dimensional guidance law could be designed in a two-dimensional plane and the difficulty of guidance law design is reduced.

A two-dimensional guidance law for three-dimensional space is derived by bringing the estimation for target maneuver.

Finally, simulation for the proposed guidance law is taken and compared with pure proportional navigation.

The simulation results demonstrate that the proposed guidance law can be applied to air-to-ground missiles.
