摘要
为提升主被动多基地声呐浮标阵对潜艇目标定位的精度与稳定性,提出了对搭载卫星模块的数字浮标使用北斗差分定位法进行定位的方案,分析了产生误差的主要因素,构建了系统误差矩阵模型,定义了一种量化反映定位稳定性的参数。最后使用加权总体最小二乘方法对北斗卫星系统单点定位与差分定位条件下T-RN型主被动全向多基地浮标阵对潜定位性能进行了仿真,结果表明:采取北斗卫星差分定位法的浮标阵无论在误差值平均值还是稳定性上都具有一定优势,增加阵元个数与减小浮标对接收回波信号的时间测量误差也可以有效提高定位精度与稳定性。仿真结果对多基地浮标阵定位的实际应用具有参考价值。
In order to improve the accuracy and stability of multi-base buoy array to submarine target positioning,the main factors of error were analyzed,the systematic error matrix model was constructed,and a stability parameter was defined to reflect the positioning stability.Finally using weighted least-square method of beidou satellite system under the condition of single point positioning and differential positioning main passive buoy array positioning error for omnidirectional multiple base were simulated.The results show that the method of difference beidou satellite positioning buoy array in average error value have certain advantages in stability,increase the array element number and reduce the buoy to echo signal time measurement error and can effectively reduce the positioning error increases the positioning stability.The simulation results have reference value to the practical application of multi-base buoy array positioning.
