“…where b L q and b θ q are the solutions of the error-free magnitude formula, and the phase is used to further estimate the source position. It is shown in [27] and [28] that there is an uncertain phase factor between the phase difference generated by the distance difference and the phase of the steering vector. In this paper, the idea of accurate estimation in [27] is used.…”

“…海洋资源勘探与海底目标识别在海洋信息感知与 交互融合领域应用愈来愈广泛 [1]。探测方法主要依托 于搭载海洋航行平台的声学设备在进行水下作业时对 信息数据的感知,利用布放在海面的浮标单元作为中 继节点,将解算数据实时传输至岸基单元,实现对水 下目标位置信息的显示与控制 [2]。 水下目标高精度定位探测技术根据所处试验环境与 战术指标分为两种:一种是目标具备自身发射脉冲信号 并接收回波进行解算,即主动探测方式,另一种是自身 不具备发射信号能力,但具备探测声源实际位置,即被 动探测方式 [3][4]。在实际工程应用中,主动探测常常由 于良好的抗干扰性被应用于水下声学感知与海底地形地 貌成像领域,而被动定位具备良好的定位探测效果,被 人们经常应用于合作目标定位跟踪与航行安全保障等领 域。目前最为常见的水下目标高精度三维定位方法是基 于中继浮标单元的定位解算技术 [5][6][7]12]。其中,目标搭 载信标有规律的发射脉冲信号,中继浮标作为接收单元 完成对编码脉冲信号的特征提取与时延信息估计 [8][9][10]。 由于水声信道的特殊性与时变性,脉冲声信号的能量也 会随着浮标阵元间隔增大而逐渐衰减,使得浮标在解算 脉冲信号的过程中受到众多环境因素干扰,造成对时延 估计精度的影响 [11,13]…”

“…Therefore, the algorithm in this paper does not need the support of the whole network synchronization clock or NTP protocol, and can directly use the system clock of the sender. It can be seen from equation ( 6) that the algorithm in this paper only needs to process the NTP absolute time in the first RTCPSR packet as the common clock reference of subsequent audio and video media packets [12].…”
