AWR1843手册中的
“Programmable Phase Rotators in Transmit Path to Enable Beam Forming”和
“The three transmit channels can be operated up to a maximum of two at a time (simultaneously) for transmit beamforming purpose as required; whereas the fur receive channels can all be operated simultaneously”中所描述的波束成形具体是用来做什么的？是为了实现波束扫描吗？还是有其他的用途？
