介绍了什么是波束形成；以及波束形成各种基本知识及原理，介绍了阵列理论； Beamforming is a signal processing technique used in arrays for directional signal transmission or reception.This is achieved by combining elements in the array in away where signals at particular angles experience constructive interference and while others experience destructive interference. Beamforming can be used at both the transmitting and receiving ends in order to achieve spatial selectivity. The improvement compared with an omnidirectional reception/ transmission is known as the receive/transmit gain (or loss).
