摘　　要：火箭助飞鱼雷海上落点是影响其命中精度的重要参数,在试验测量时,用于水声定位的海上浮标可能会出现缺失而影响其测量精度。本文利用Matlab软件对火箭助飞鱼雷海上落点测量浮标预设阵型进行了仿真研究,分析了缺失部分浮标对测量精度的影响,给出了缺失浮标数量及阵型最低条件,即当12个浮标中缺失4个浮标且阵型不对称时,测量精度会迅速下降。研究结果表明,在落点测控过程中,如果文中的预设浮标阵型不满足最低条件,应重新调整浮标。该研究可为海上实际试验指挥决策提供技术支撑。Absence of buoys used for hydroacoustic localization in sea trial may reduce measurement accuracy of water entry point of a rocket-assisted torpedo.In this paper,the preset buoy array for measuring water entry point of a rocket-assisted torpedo is simulated with the software Matlab,and the effect of absence of some buoys on measurement accuracy of water entry point is analyzed.The results show that when absent buoys and buoy array reach to the lower limit,i.e.4 of 12 buoys are absent and the buoy array is asymmetric,the measurement accuracy will decrease rapidly.Therefore,if the topology of preset buoy array does not satisfy the lower limit,the array must be adjusted.
