摘　　要：气象雷达在运行的过程中,定点控制的精度对气象预报的准确性具有重要的影响。针对气象雷达在运行的过程中精确定位的需要,在气象雷达的伺服控制系统中,采用2片16位高精度的旋变数字转换器AD2S1210分别作为方位角和俯仰角的解码器,用于采集方位旋转变压器和俯仰旋转变压器输出的角度信号,并结合PID控制算法,使气象雷达在定点运动的过程中,其俯仰角定位误差不大于0.01°,方位角定位误差不大于0.02°,且整体运行平稳。实验结果表明AD2S1210的性能非常优良。The precision of set-point control has an important influence on the accuracy of meteorological forecasts. In order to meet the needs of precision servo control of meteorological radar,two 16 bit and high-precision resolver-to-digital converters AD2 S1210 are used as the angle decoder of azimuth and pitch angle in the servo control system of meteorological radar to collect the angle signals of azimuth resolver and pitching resolver. Combined with the PID control algorithm,the error of actual pitch angle and expected pitch angle is not more than 0.01°,and the error of actual azimuth angle and expected azimuth angle is not more than 0.02 °,and the servo control system of meteorological radar works very well. The experimental results show that the performance of AD2 S1210 is excellent.
