Discussion on Graphic Expression of Stability of Target Motion Factors

Navy Submarine Academy, Qingdao 266199, China

摘要

摘要: 文中提出将目标运动要素解算结果进行图形表达的概念, 对于等速直航目标, 以声速有限的单站纯方位方法估计其运动要素, 并以计算机绘制出最近若干个目标位置点估计、目标速度估计、目标方位观测误差均方差估计, 以此表达运动要素解算结果的稳定性, 便于决策者直观理解及提高采用目标运动要素的效率。同时发现,可以用目标方位观测误差均方差估计的性质判断目标可能的机动, 以此作为重置解算的基础, 用以更好地为鱼雷作战应用提供参考。

Abstract: A concept of expressing calculation results of target motion factors graphically is proposed. For a straight running target with constant velocity, the target motion factors are estimated by the one station bearing-only method with finite sound speed. A computer is used to draw a graph of recent several target estimations in terms of position, velocity, and mean square deviation of bearing observing errors. This graph may express the stability of calculation results of the target motion factors to help decision-maker sunder stand intuitively and improve decision efficiency of choosing target motion factors. It is found that the estimated properties of the mean square deviation of bearing observing errors can be used to judge target maneuver, and the judgment can be taken as a basis to reset calculation. This study may provide a reference for torpedo operational application.
