• 1. Time-delay of arrival: 到达时间差 | 估计
• 2. time delay of arrival: 基于到达时间差 | 到达时延 | 时问延迟的定位 | 时间延迟
• 3. time delay and direction-of-arrival estimation: 时延和方向角估计

• 1.Time delay estimation was widely used in many areas such as target localization, directions of arrival (DOA) estimation.
  多途时延估计广泛的应用于目标定位，波达方向估计等领域，因此具有十分重要的意义。
