Improving divert capability of interceptor in high altitude situation with the help of thrusters is quite important way to increase the agility and hit accuracy. This paper concerns direct force assignment logic and method for well coordinating with aerodynamic force. A predictive miss distance computation method was introduced by taking target constant acceleration maneuvering into consideration. Direct force commend was computed from miss distance in the light of reducing predictive miss distance leading missile to hit target, and aero force was used to correct remainder miss distance based on predictive guidance law. Thus, a thrust-aerodynamic-force blended guidance strategy was developed by assigning direct and aero force in different way. The proposed method was compared with aerodynamic force controller with classic proportional navigation guidance (PNG) and thrust-aerodynamic-force blended control strategy. Simulation results show that direct forces is very helpful to acquire high hit precision, and strategy developed is more fuel-saving comparing to thrust-aerodynamic-force blended control strategy.
