摘　　要：测量精度的高低是表征一个测量系统技术性能优劣的重要指标。根据非同步长基线水声跟踪定位系统的定位原理,建立了系统误差分析数学模型,进行了大量的综合精度仿真计算,分析了交会误差、测时误差、基元位置误差等对定位精度的影响,以及目标在阵内阵外的误差分布情况。High or low of the precision is the important guideline that expresses performance of the measure system.According to the location theory of asynchronous long baseline underwater acoustic location system,a mathematic model is established for system error analyzing,a lot of integrative precision emulation calculation are put up,and the effect of intersectant error is analyzed,time measure error,bouy position error,and the error distributing when the target is inside the array or outside the array.
