为利用小型相控阵实现高频地波雷达对中远距离大范围海域表面状态的有效监测 ,提出了一种以优化八木天线为单元的收发共用相控阵 ,实施单排激励。这种设计使整个雷达系统的硬件配置和相控天线阵布阵简单 ,较好地解决了收发共用造成的阻抗匹配困难 ,便于实现宽窄波束、软硬件技术结合的收发共用相控天线阵的设计路线。
In order to effectively monitor the surface state of large-scale long-range and large-area sea-surface using high-frequency ground wave radar with small phased array, a new type of excitation system with optimized Yagi antenna is proposed. This design makes the hardware configuration of the whole radar system and the phased array antenna array simple and solves the impedance matching difficulty caused by the common receiving and dispatching and facilitates the design of the wideband and the narrow beam as well as the combined transmitting and receiving phased array antenna with hardware and software technology route.
