低成本风廓线雷达相控阵天线设计

摘要

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 shift-ers are required in the antenna system to achieve five beams scanning correspondingly. Using the method can sim-plify the beam control system and thus reduce complexity and cost of the antenna system.%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。
