Time Difference of Arrival
摘要
Estimating the time delayTime delay between received signals is fundamental to determining the direction of arrival (DOA)Direction of Arrival (DoA) [1]. The performance of direction-finding systems critically depends on both the characteristics of the signal and the geometry of the sensor arraySensor array in the TDOA approach. In particular, sensor spacing plays a pivotal role, with conventional designs typically assuming half-wavelength separation.
