The phase and amplitude weighting of the phased array acoustic logging transmitter can be controlled by the two kinds of exciting signal sources.
利用这两种信号源可以对相控线阵声波辐射器进行相位和幅度加权控制。

A makeup of the multi-element linear transducer array system and Experimental setup were described in detail, besides the application of phase-controlled algorithm in multi-element transducer array.
It is expected that this RF phase shifter will be widely used in optically controlled phased array radar systems and phasecontrolled communication systems.
