结合设计实例详细论述了通信延时对雷达伺服系统跟踪精度的影响,提出了采用常增益滤波法的解决方案,并通过仿真和试验结果加以验证。工程实践表明,根据目标的运动特性,选择匹配的常增益滤波器,将有助于克服通信延时的不利影响,对提高伺服系统的跟踪精度有较大的作用。

This paper discusses the effect of communication delay on radar servo system's track precision based on an engineering design,and offers a solution which applies fixed-gain filter.It has proved useful by simulation and practical test.Through the engineering experience,it can be drawn a conclusion that if choose the right fixed-gain filter according the characteristic of target movement,it will be helpful to reduce the bad effect of communication delay,and to improve track precision of radar servo system at the same time.
