| 摘要 |
长基线阵球面交汇定位系统中．布阵方式将影响水下目标的定位精度。首然后通过仿真定量分析了不同布阵方式下的定位误差。分析结果表明，水平阵无平面定位，定深则需由深度传感器完成。另外。当测量阵的孔径较大且水下目标最小。 |
| 摘要_英文 |
The position of the sensors plays St very important role in long baseline positioning system．If the position is designed inappropriately，there will be a great error on source location． Based on the positioning theory，a quantitative analysis of positioning error is discussed by simulatiom The simulation results show that the array in a plane would cause large locating error in vertical direction， and such arrays would generally be used for locatingthe source in 2D space．The depth of the source should be determined by the depth sensors．In addition，the position error is the smallest only when the aperture of the array is large and the source locates directly under the array． |
