摘要

摘要: 在移动长基线定位系统中, 无人水上舰船(USV)的队形以及与定位目标之间的位置关系对定位精度有着重要的影响。本文基于球面交会法, 设计了一种精度评价函数。利用此精度评价函数分别研究了多USV结构对定位精度的影响; 被定位目标与多USV阵型间的位置关系对定位精度的影响; 量测精度对定位精度的影响。通过推理证明, 得到被定位目标在4艘USV组成的正方形基阵中垂线上时定位精度最高的结论。仿真结果表明, USV队形对定位精度有显著影响。

Abstract: In the positioning system with moving long baseline, formation of unmanned surface vehicles(USVs) and their relative position to the positioned target significantly influence the positioning accuracy. In this paper, we design an accuracy evaluation function based on spherical intersection method to investigate the factors influencing the positioning accuracy, such as the USVs formation, the relative position of target and the USVs formation, and the measurement pre-cision. Inference proves that the highest positioning accuracy can be achieved when the target is located in the perpen-dicular bisector of a square array which is composed of four USVs. Simulation result shows that USVs formation has a significant influence on the positioning accuracy.
