Sensor arrays provide additional degree of freedom in the spatial domain compared to a single antenna, which, with the aid of advanced signal processing algorithms, can be exploited for interference suppression/beamforming, direction of arrival estimation, and target tracking and localization. While two prominent technologies in 5G/6G communication system, i.e., massive MIMO and millimeter (mm) wave communication, generally demand massive antennas, significant advances in antenna arrays are expected to satisfy the requirement of thousands of contemporaneously connected devices. Array signal processing has aroused considerable attentions, and various applications contain 5G/6G communications, MIMO radar and satellite navigation.

与单个天线相比，传感器阵列在空间域中提供了额外的自由度，借助先进的信号处理算法，传感器阵列可用于干扰抑制/波束形成，到达方向估计以及目标跟踪和定位。虽然5G / 6G通信系统中的两项杰出技术（即大规模MIMO和毫米波通信）通常都需要大规模天线，但是天线阵列的重大进步有望满足成千上万个同时连接设备的需求。阵列信号处理引起了相当大的关注，各种各样的应用包括5G / 6G通信，MIMO雷达和卫星导航。
