基于AT89S52单片机的测速雷达伺服控制系统设计

本文设计的伺服系统首先通过RS485串行接口实现上位机（PC机）与下位机（单片机）的远程通讯，完成程控跟踪数据和触发控制信号的传输；其次，通过以AT89S52为核心的主控板，实现转动控制信号和角度指示信号的处理与输出；最后，结合电机驱动模块和显示模块，实现测速雷达天线俯仰程控跟踪转动和当前天线角度实时显示等功能。实验证明，本伺服系统各功能模块工作正常，跟踪精度完全满足测速雷达系统的要求。同时，本系统还具有低成本、操作简单、使用方便和可靠性高的特点，具有良好的推广应用价值。

Design of servo system for velocity-measurement radar based on AT89S52

In this paper,a servo system is designed for long-distance communication between the host computer (PC) and the next-bit machine (SCM) through the RS485 serial interface,and also for the intercommunion of the program-controlled tracking data and the trigger control signals. Then,the AT89S52 control panel is built to deal with the processing and outputing of the rotation control signal and the angle indication signal. Finally,a whole functional system combined with motor drive module and display module is ma...
