为了提高机场天气雷达伺服系统的可靠性，同时降低系统复杂度，文中设计了一种单双机混合体制的新型伺服系统，主要研究了其组成、控制方案以及软硬件关键设计等。该设计已成功应用于国际机场C波段多普勒天气雷达，相对于单机伺服系统，提高了系统的可靠性和可维护性；相对于双机系统，又减少了不必要的设备和成本。

A new servo system with single-double machine configuration is designed for improving servo system reliability of weather radar at airport and reducing system complexity. System composition, control scheme and key design of software and hardware are mainly studied. Moreover, the new servo system is applied in C-band Doppler weather radar at an international airport. It improves system's reliability and maintainability relative to the single system, meanwhile reduces the amount of unnecessary equipment and cost relative to the double system.
