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。
The delay or difference in the arrival time of seismic events that can result from weathering of the rocks or variations in geologic structures in the subsurface.
地震同相轴到达时的延迟或差异，这是由于岩石的风化层和地下地质体的变化产生的。
With choosing signal time delay and element location of nonuniform array properly, the estimated frequencies and 2 D directions of arrival are unambiguous.
适当地选取时延和非均匀阵列阵元位置，该方法的信号频率和2D到达方向估计无模糊。
