By the examples computation, the effects of the damage degree, damage location and zone on the amplitude and the arrivaltimeof the received wave were quantitatively analyzed.
通过实例计算，定量地分析了结构内部损伤度、损伤位置和损伤区域大小对接收波幅值和波到达时间的影响。

With choosing signal time delay and element locationof 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2 D到达方向估计无模糊。

In this paper, the system model of TDOA location has been established on the Communication Countermeasure Simulation Platform based on the working principle oftime difference of arrival technique.
