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。 In order to improve the reliability of the airport weather radar servo system and reduce the complexity of the system, a new type of servo system with single and double hybrid system is designed in this paper. Its components, control schemes and key hardware and software design are mainly studied. The design has been successfully applied to the International Airport C-band Doppler weather radar, relative to the stand-alone servo system to improve the reliability and maintainability of the system; Compared with the two-plane system, but also reduces unnecessary equipment and costs.
