Abstract: Aiming at the maneuvering penetration problem of near space vehicles, we design and analyze the maneuvering penetration strategy of the vehicles during midcourse guidance based on the differential game theory. First, the attack-defense confrontation problem is transformed into a two-person zero-sum game problem, and a quadratic objective function is designed. Secondly, considering the problem of insufficient computing power of the vehicle, we take reasonable assumptions to obtain the analytical solution of the game problem for convenient practical applications. Finally, the maneuvering penetration strategy based on the differential game theory is simulated and verified. The results show that compared with the sinusoidal maneuver during the midcourse guidance, this strategy not only reduces 54.3% of energy consumption by the vehicle, but increases 58.6% of the energy consumption by the interceptor, therefore significantly raising the penetration ability of the vehicle during terminal guidance.
