非均匀线阵DOA估计可识别条件的推导
A Derivation of Identifiable Condition for Non-Uniform Linear Array DOA Estimation
摘要:
当阵元间距大于$λ/2$时,均匀线阵会产生相位模糊。这个问题在波达方向(DOA)估计中存在,可以通过设计合适的传感器结构来解决.在这项工作中,我们推导出可识别的条件,双波达方向估计。
英文摘要:
Phase ambiguity happens in uniform linear arrays (ULAs) when the sensor distance is greater than $λ/2$. This problem in direction of arrival (DOA) estimation and can be solved by designing a proper sensor configuration. In this work, we derive the identifiable condition for ULA DOA estimation.
