Maximum-information guidance for homing missiles

A recently-defined information index is used to enhance the information content of minimum-control-effort trajectories for the homing missile intercept problem. Optimal planar intercept trajectories are obtained for a performance index which is control effort weighted by position information content. The missile and target are assumed to be operating at constant speed. The shooting method is used to compute the optimal paths; but because of the simplicity of the model, on-line optimization yielding a guidance law with information enhancement should be possible.
