相控阵雷达体制是由控制每个天线单元的相位来控制空间的波束合成,从而改变合成波束的指向来实现电扫描的一种先进雷达体制。它有多种馈电形式,其中之一是采用多个发射机并馈形式。但是,并馈形式有一个突出的问题,就是必须保持并馈运用的发射机之间有一个稳定的相对相位关系。否则,就要影响波控计算机对天线单元移相控制。
Phased array radar system is by controlling the phase of each antenna element to control spatial beam synthesis, thereby changing the direction of the composite beam to achieve an advanced scanning electrical radar system. It has a variety of forms of feed, one of which is the use of multiple transmitters and fed form. However, there is a prominent problem with the form of fed-in, that is, there is a stable relative phase relationship between transmitters that must be kept alive and fed. Otherwise, it will affect the wave control computer phase-shifting antenna unit control.
