第三讲 PIN管的应用(二)——相幅控制相幅控制器件,尤其是相控器件,在相控阵雷达中有广泛的用途,是相控阵雷达的关键部件之一。在相控阵雷达的每个辐射单元输入处接入电控移相器,改变其相位,可以快速地改变天线阵的相位波前,从而控制波束辐射方向。也可通过电控移相器来控制波 The third PIN tube application (b) - phase control phase amplitude control devices, especially phased-array devices, has a wide range of uses in phased array radar, phased array radar is one of the key components. In the phased array radar access to each input radiation unit phase shifter, change its phase, you can quickly change the antenna array phase wavefront, and thus control the beam radiation direction. Waves can also be controlled by electronically controlled phase shifters
