大型相控阵天线模块化设计

大型相控阵天线设备量大、系统复杂，因而具有研制周期长、成本高、使用维护复杂等特点。传统的设计方法已难以满足阵面设计的要求，进而在阵面设计中发展并广泛采用了模块化设计思想。模块逐渐从结构性模块发展到功能性模块，目前已基本实现了大型相控阵天线的模块化设计。文中以2个大型相控阵天线阵面为例，详细介绍了模块化设计的巨大优势，并提出了相控阵天线模块化设计需要继续深入开展的工作。

Modular Design for Large Phased Array Antenna

Due to large amount of equipment and complex system, large phased array antenna has the characteristics of long development period, high cost and complex operation and maintenance. Traditional design method has been difficult to meet the antenna design requirements, so modular design method is developed and widely used in the design of large phased array antenna. Modules created in the design gradually extend from structural module to functional module, and the modular design of large phased array antenna is basically realized at present. With two typical large phased array antennas as examples, great advantages of modular design are revealed comparing to traditional method, and some further in-depth studies needed for phased array antenna modular design are proposed.
