基于解析算法的声纳浮标搜潜系统定位精度分析

针对基于位置时间参数解析算法的声纳浮标阵搜潜系统的定位精度问题，采用定性和定量分析相结合的方法展开了研究。从解析定位模型出发，首先定性分析浮标自身的定位误差与传感器测时误差对航速及航向角计算的影响；然后选取评价指标，采用蒙特卡洛方法进行了仿真分析，得到了不同仿真条件下各个因素对定位精度具体的影响关系，这些结论为根据精度参数合理选择浮标阵的数量及布放阵型提供了依据。

Location Precision Analysis of Sonobuoy Searching Submarine System based on analytical algorithm

In view of location precision problem of sonobuoy searching submarine system based on analytical algorithm, analysis combined qualitative method with quantitative analysis was given. First of all, proceeding from analytical location model, the influence of the error of measuring the location and measuring the time to speed and azimuth of the target was analysed qualitatively. Then some index was select to evaluate the method, and the method of Monte-Carlo was adopted for simulation analysis. Under given simulation conditions, the concrete influence relation of these factors and location precision was given. These conclusions furnished the basis for the selection of sonobuoy quantity and distribution.
