摘　　要：传统的落点预报算法建立的被动段弹道动力学模型适用于只有地球引力、空气阻力等情况下的运动模型。实际任务中导弹被动段有机动的情况下,预报落点偏差很大。针对这个问题,分析了落点预报误差原因,并在模型加入控制力因素改进了基于四阶的"龙格-库塔"微分算法,经试验数据证明,改进后的落点预报算法误差明显小于原算法,为试验任务的脱靶量计算辅助判决起到重要作用。The passive segment trajectory dynamics model established by the conventional drop prediction algorithm is applicable to the motion model with only gravity,air resistance and so on. When the missile passive segment is maneuvering in the actual task,there is a great deviation in the forecast. This paper analyzed the reasons for this problem,and improved the fourth-order ＂runge-kutta＂differential algorithm.The error of the improved drop point prediction algorithm is obviously smaller than the original algorithm.The auxiliary judgment plays an important role in the calculation of the off-target of the test.
