中文摘要:
      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。首先从理论上对定位原理进行了讨论;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,水平阵无法实现三维定位,通常只能实现二维平面定位,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位于水平测量阵的正下方时,定位误差最小。
英文摘要:
      The position of the sensors plays a 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 simulation.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 locating the 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.
