文章针对现阶段助推滑翔飞行器的精确打击所面临的一系列误差因素做出改进,以达到精确制导的目的。首先,关于助推滑翔飞行器(CAV-H)再入制导问题,在滑翔段和下压段分别使用预测校正制导和比例导引法以达到对地精确快速打击目标;其次,针对弹道的震荡问题采用类似PD控制的方法,用牛顿-拉夫森迭代法对倾侧角进行修正;最后,通过仿真验证滑翔段的制导方法的有效性。 The article aims at improving a series of error factors which are facing the precise strike of the boosting gliding aircraft at present to achieve the purpose of precise guidance. First of all, on the guided reentry of the gliding glide vehicle (CAV-H), the guidance of the guidance system and the proportional guidance method are used respectively in the gliding section and the depressing section to achieve the target of precise and rapid attack on the ground. Secondly, A similar PD control method is used to correct the roll angle by the Newton-Raphson iteration method. Finally, the effectiveness of the gliding-section guidance method is verified by simulation.
