All seismic signal acquisition nodes must be synchronized so that they have the same sampling time for seismic signal acquisition in a distributed chained system with a large number of acquisition nodes. However, the propagation delay generated by the long-distance transmission link causes a synchronization acquisition error. In order to correct accurately the synchronization acquisition error, getting...
Gain and phase errors sensitivity is an issue common to all high-resolution direction-of-arrival estimators. In this paper, we first provide the conventional and improved data models. Second, based on the conventional data model, an algorithm called estimation algorithm for the conventional data model (EACDM) is proposed to estimate the gain and phase errors existing in the sensor array for the uniform...
