摘要
论述了AGC在单脉冲雷达接收机中的作用及其控制原理,阐明了AGC电路与伺服系统之间的关系。通过调整AGC的参数,可以使AGC与伺服系统达到最佳匹配,消除AGC带来的跟踪抖动和跟踪速度不够等问题。重点分析和讨论了自动增益控制时间常数与伺服系统的关系,通过实际工程应用,指出了需要注意的一些问题,为以后进一步开展相关工作提出了具有实际指导意义的理论分析方法。
The function of AGC in monopulse radar receiver and its operational principle were described.The relationship between AGC circuit and servo-system was explained.Optimal match between AGC and servo-system could be obtained,and problems,such as tracking dithering and inadequate tracking speed,associated with AGC could be eliminated by adjusting parameters of AGC circuit.The relationship between time constant of AGC and servo-system was analyzed and discussed in particular.Issues to be taken into account in engineering applications were pointed out,which may serve as useful guidance for future work.
