摘要: 针对飞行器机动突防问题,基于微分对策理论对飞行器在攻防对抗中制导阶段的机动突防策略进行设计与分析。首先将攻防对抗问题转化为二人零和博弈问题,并设计了二次型目标函数;其次,考虑到飞行器计算能力不足的问题,采取了适当假设以得到博弈问题的解析解,便于实际应用;最后对该机动突防策略进行了仿真验证,结果表明在攻防对抗中制导阶段,飞行器采用微分对策制导律,相较于正弦机动不仅减少自身54.3%的能量消耗,而且增加了拦截器58.6%的能量消耗,将显著增加飞行器末制导段对抗突防能力。

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.

Key words: near space, differential game, midcourse guidance, attack-defense confrontation, maneuver penetration strategies
