摘要
针对主动全向声纳浮标定位目标算法和定位误差问题,依据"纯距离测量"定位的最小二乘算法,给出了定位误差方差阵的迭代计算方法和计算流程.采用蒙特卡洛仿真方法,统计分析了定位算法的精度;对比分析了定位误差均方差理论计算值和目标位置仿真结果的均方根误差,给出了定位算法的精度,验证了定位误差算法的正确性.
Aiming at the problem of nondirectional active sonobuoy target location, and according to the linear least squares method of rangeonly target location, the paper presents the iterative arithmetic and calculating flow of the location error variance matrix. The precision of the location algorithm is analyzed by the Monte Carlo simulation. The theoretical standard deviation of location error and the RMSE of target simulating posi tion are contrasted, and the precision of the location algorithm is confirmed by the result.
