摘　　要：首先对海上运动平台多站时差定位系统中几种典型定位算法进行了理论分析,然后讨论了双曲直接解法、Chan算法和近似极大似然定位算法对系统定时误差和站位误差的影响。在仿真分析下进行了定位性能分析。最终结合海面上的复杂环境背景,选择Chan算法来进行定位解算。This paper firstly theoretically analyzes several typical positioning algorithms in the multi-station time difference of arrival(TDOA)positioning system of the offshore mobile platform,and then discusses the influence of hyperbolic direct solution method,Chan algorithm and approximate maximum likelihood positioning algorithm on the system timing error and station site error.The positioning performance analysis under the simulation analysis is carried out.Finally,combined with the complex environmental background on sea surface,the Chan algorithm is selected for the positioning solution.
