摘　　要：实时性是跟踪雷达伺服系统的重要性能,是其伺服带宽、加速度、速度等指标的综合反应。本文使用了PC104和单片机W77E58的双嵌入式系统设计某型号自动跟踪测速雷达的伺服系统,可以更好地解决雷达跟踪的实时性问题,大大减小伺服周期。而且,其结构模块化,设计简单。实验表明,伺服系统具有很好的跟踪性能。Real-timeness is the important performance in the servo system of an automatic radar, since it expresses the servo band, acceleration and velocity. The paper uses a double embedded system based on PC104 and SCM to design an au-tomatic velocity-measured radar＇s servo system in order to promote the real-timeness of radar tracking, thus reducing the servo cycle. In addition, the system is modularized and simple-to-design. Experimental results show that the system has good tracking performance.
