为提高机动平台水下活动时的生存概率，以平台及目标运动的向量误差构建相对误差散布域。分析目标散布要素和平台散布要素，以目标位置为中心点建立相对位置散布图，研究各向量误差的作用机理；以水下平台航向作为基准轴，依据时变的向量误差推导出合成误差椭圆要素；由平台和目标的初始态势及纯方位解要素的均方误差作为初始条件，仿真得到不确定位置散布域，以此作为水下平台规避威胁目标的依据。
In order to improve the survival probability of submarine underwater activities, the relative error dispersion domain is constructed based on the vector error of the submarine and target motion. Analyze the target dispersion elements and the submarine dispersion elements, establish a relative position dispersion map with the target position as the center point, and study the mechanism of each vector error. Use the submarine heading as the reference axis, and derive the composite error ellipse element based on the time-varying vector error. With the initial situation of the submarine and the target and the mean square error of the pure azimuth solution elements as the initial conditions, the simulation obtains the uncertain position dispersion domain, which is used as the basis for the submarine to avoid the threat target.
