相控阵天线相控阵天线利用移相器补偿信号到达辐射元时间的差异，从而控制波束方向。各个辐射无所接收到的信号通过各自对应的移相器后相加。移相器要预先调整好，以便各个信号可以同相相加。在图１的上半部分，因为各个信号同相到达辐射元，故移相器设定值均相等。而在图... Phased Array Antenna Phased array antennas use phase shifters to compensate for the difference in signal arrival time of radiating elements and thereby control the beam direction. The signals that are not received by each radiation are summed by the respective phase shifters. The phase shifters must be adjusted in advance so that the signals can be added in phase. In the upper part of Figure 1, the phase shifter settings are equal because each signal reaches the radiating element in phase. In the figure
