Mixed strategy guidance based on target maneuver detection

With the general separation theorem consideration, two mixed strategy guidance approaches are presented. All based on the target maneuver detection, one approach mixes two available differential game guidance laws to reduce the effect of the estimation delay; the other incorporates one more proposed modified gain differential game guidance law, which increases the lateral acceleration command for estimation delay and short remaining time consideration. The simulation results show that these two approaches can improve the system performance significantly and the second approach has the best performance.
