雷达天线平台的水平度严重影响雷达的测量和跟踪精度，文中介绍了一种基于单片机和可编程逻辑器件（CPLD）的雷达天线平台自动调平系统，系统简单可靠，主要采用四条支撑腿联动方法，在最短时间内自动调平天线载车，并将天线平台倾斜度实时传送给雷达主机，从而大大地提高了雷达的测量和跟踪精度，以及雷达天线的架设和撤收速度。

The horizon of radar antenna pedestal affects the accuracy of target tracking and measuring to the radar seriously.In this paper,an automatic level system is presented for the radar antenna pedestal based on the SCM and CPLD.The system is easy and reliable to adjust,and adjust the antenna to level in the least time automatically with four long span's linkage.It sends the gradient of the antenna pedestal to the host radar,so the accuracy of target tracking and measuring,and the speed of antenna erection and withdraw have been improved greatly.
