摘要: 为解决单、双光学浮标无法获得目标全要素信息的问题, 文中基于声学目标运动要素解算技术, 提出了一种多光学浮标联合定位算法, 建立了包含浮标定位误差、观测时间误差和光学观测模糊误差的光学浮标观测数学模型, 利用蒙特卡洛仿真方法给出了考虑上述误差并针对机动目标不同数量光学浮标的定位精度指标, 同时分析了各因素对多浮标联合定位的影响。文中研究为光学浮标的工程应用提供了数据支撑。Abstract: To solve the problem that single or double optical buoys cannot obtain all-elements information of a target, based on the technique of calculating the moving elements of acoustic target, an algorithm for multi-optical buoys joint localization is presented in this paper. A mathematical model is established for the observation of optical buoys including positioning error, observation time error, and optical observation blur error. Utilizing the Monte-Carlo simulation method, the localization accuracy index of different number of optical buoys for maneuvering target considering all the above-mentioned errors is provided, and the effect of each factor on the joint localization of multi-optical buoys is analyzed simultaneously. The research provides data support for the engineering application of optical buoy.
