引言六十和七十年代期间,微波集成电路的发展使有可能考虑采用有源孔径相控阵天线。已实现和验证了若干种这样的系统。一个早期的例子是得克萨斯仪器公司在六十年代未期研制的分子电子学雷达阵列(MERA)系统。但是,在大多数情况下,这样的系统仍然是昂贵的和不现实的,因为其成本太高,而且所需的微波部件的生产重复性差。最近,部署了诸如PAVE/PAWS和丹麦眼镜蛇这样的大型相控阵雷达。但是,它们的特点是既庞大又昂贵,且一种雷达只建造一部。七十和八十年间单片微波集成电路(MMIC)和小型混合微波集成电路(MH
Introduction The development of microwave integrated circuits during the 1960s and 1970s made it possible to consider the use of active-aperture phased array antennas. Several such systems have been implemented and validated. An early example is the molecular electronics Radar Array (MERA) system that Texas Instruments did not develop in the 1960s. However, in most cases, such systems are still expensive and unrealistic because of their high cost and the poor reproducibility of the required microwave components. Recently, large phased array radars such as the PAVE / PAWS and the Danish Cobra have been deployed. However, they are both bulky and expensive, and only one radar is built. Seventy and eighty years of monolithic microwave integrated circuits (MMIC) and small hybrid microwave integrated circuits (MH
