摘要
给出了一种新型的舰载雷达数字伺服控制系统的设计。采用坐标变换技术在雷达天线的方位和俯仰轴上对船摇姿态角 (横摇角R、纵摇角P和航向角H)进行角度实时补偿以达到稳定雷达天线的作用。控制系统采用了变速积分PID及非线性PID等新颖的控制算法 ,可满足雷达天线环扫、扇扫、扇扫自适应、定位跟踪及俯仰控制等技术要求 ,并给出了环扫、扇扫、扇扫自适应及定位跟踪等功能的实现方法以及性能测试结果。
The design of a new type of the digital servo control system of the shipborne radar is introduced in this paper.The coordinate transformation technology is adopted to compensate with real time the attitude angles (rolling angle R,pitch angle P and course angle H)of the swinging ship on the azimuth and elevating axis of the radar antenna in order to stabilize the radar antenna.The control system adopts the new control algorithms,such as variable speed integrating PID and non linear PID,meeting the technical requirements of the loop scan,sector scan,sector scan adaption,locating track and elevating control of the radar antenna.The realizing methods of the functions,such as loop scan,sector scan,sector scan adaption and locating track and the performance test results are given.
