The direction of Radar Target is got by antenna beam scanning.
雷达测定目标的方向是利用天线波束的扫描来实现的。
Its antenna beam scanning entirely electronically controlled beam scanning speed is not only high, but the number of beams, movement pattern can be arbitrarily controlled.
其天线波束的扫描完全用电子的方式控制，不但波束的扫描速度极高，而且波束的数目、运动方式都可以随意的控制。
On this basis, the problem for the beam broadening and scanning of the phased array antenna is studied.
在此基础上，对一维相控阵天线的波束展宽和扫描问题进行了研究。
Finally, the beam broadening and scanning problems for the phased array antenna are studied.
