潜艇不机动纯方位解算编队目标运动要素方法

Method for Bearing Only TMA without Maneuvering for Submarine

针对单艘潜艇纯方位目标定位必须潜艇机动才能使算法收敛的问题,首次采用几何分析法研究了潜艇不机动情况下,解算编队目标运动要素的方法;然后,基于最小二乘法,给出了具体的解算模型,并给定态势,进行实例仿真。证明该算法能够满足潜艇隐蔽对编队目标定位的需要,进一步丰富了潜艇纯方位目标定位方法。

In order to make the arithmetic of bearing only TMA（ target motion analysis） with single submarine converge, the submarine must to maneuver at least one time. Through geometrical analysis, the paper researches the TMA method on sur- face formation under the submarine doesn＇t maneuvering, and then the paper set up the calculation models based on least- squares. Example proved that this arithmetic can satisfy the need of TMA on surface formation for snugly navigating subma- rine, can also enrich the TMA method for single submarine.
