采用两套接收系统,利用两天线方向上的差别,造成两接收系统的信号波与干扰波的比值不同,然后进行叠加,抵消掉干扰波而保留信号波。
Adopt two sets of receiving systems, make use of the difference in the direction of two aerials, cause the ratio of the signal wave of the two receiving systems to the interference wave is different, then carry on the superposition, counteract the interference wave and keep the signal wave.
