摘要
本文针对风廓线雷达相控阵天线波束扫描特点,提出一种利用周期同相馈电法与驻波子阵形式相结合的设计方案。天线系统只需要五个移相器就可以实现相应的五波束扫描,简化了波束控制系统,降低了天线系统的复杂度与成本。
Considering the beam scanning characteristics of phased array antenna for wind profiling radar, a design concept combining cycle in phase feeding with standing wave subarray is proposed, by which only five phase shifters are required in the antenna system to achieve five beams scanning correspondingly. Using the method can simplify the beam control system and thus reduce complexity and cost of the antenna system.
