摘　　要：针对基座运动对于飞行器落点偏差影响问题,从基座平移运动和摇摆运动2个方面,基于弹道落点偏差产生的物理与数学原理,采用理论分析与计算推导相结合的方法,分别研究了基座水平速度、升沉速度、纵摇、横摇和偏航摇对落点偏差的影响机理,建立了基座运动状态对飞行器落点的误差传播计算模型,并通过算例分析了这几种因素对于飞行器落点偏差的影响程度,给出了提高落点精度的相应建议与方法。Aiming at the influence of moving base on ballistic aircraft landing point deviation,from two aspects of translation motion and swing motion,based on physical and mathematical principles of missile landing point deviation,the method that is combining theoretical analysis and computational derivation is applied.And the influence mechanism of moving base’s horizontal speed,pitching,longitudinal shaking,horizontal shaking and yaw shaking on missile’s landing point deviation is studied respectively.And the error propagation calculation model of moving base motion state for landing point is established.Moreover,the influence grade of these factors on the missile landing point deviation is analyzed through an example,and suggestions and methods for improving the landing point accuracy are provided.
