在雷达天线技术中革新最显著的是相控阵天线。80年代初开发了使用铁氧体移相器和PIN二极管移相器作为功能元件的无源相控阵天线。这种天线单元数较少,经济性好,主要用作仰角波束扫描共用馈电无源相控阵天线或者阵列馈电的反射镜型一元波束扫描天线。在功能元件方面开发出可逆型和不可逆型大功率铁氧体移相器和起动电路。不可逆型波
The most significant innovation in radar antenna technology is the phased array antenna. In the early 1980s, passive phased array antennas using ferrite phase shifters and PIN diode phase shifters as functional components were developed. This kind of antenna unit is less in number and economy, and it is mainly used as a reflector-type uniaxial beam scanning antenna with a shared feed passive phased array antenna or an array feed. Developed in the functional components of reversible and irreversible high-power ferrite phase shifter and starting circuit. Irreversible wave
