摘　　要：在雷达伺服系统的基础上，针对精密跟踪测量雷达的特点，以方位．俯仰型大口径雷达作为研究对象，经过详细的理论分析、计算机仿真、实际跟星实验，实现了不用距离信息、仅用天线角度和跟踪误差完成目标前馈的复合控制技术。在保证伺服系统稳定性能不变的情况下，复合控制技术使伺服系统的稳态性能和动态性能有了很大改善，减弱了雷达跟踪快速运动目标时的动态滞后问题，提高雷达的跟踪精度，完全可以满足大口径雷达对II型伺服系统提出的品质要求。In accordance with the characteristics of precise measurement radar, the article in which takes the large diameter radar with azimuth-elevation pedestal as study target on the basis of radar servo system, realizes the accomplishment of compound control technology of target feedforward only using both antenna angle and tracking difference but not the distance message after detailed theoretical analysis, computer simulation and practically track-satellite experiment. Both steady state and dynamic state performance of servo system are improved greatly by the compound control technology and helpless steady state and dynamic state lag are reduced when the radar tracks the moving target in high speed, which improves the tracking accuracy of radar and fully meets the requirements of figure of merit proposed by the large-aperture radar to Model II Servo System.
