The investigations of the two previous years dealt with a constant velocity missile model. The last year activities were oriented to evaluate the validity of the previously obtained results for more realistic variable speed missile models. For this purpose an aerodynamic model provided by WL/MNAG was used. Moreover, acceleration limits were imposed separately on each guidance channel, simulating trimmed angle of attack limits. The study indicated that the guidance law used in the previous (constant speed) analysis has to be modified and incorporate a term for compensating the effect of missile longitudinal acceleration. With this modification the homing performance of a variable speed missile using mixed strategy guidance is very similar to the performance of a constant speed model, as long as the terminal maneuverability of the missile remains unchanged.
