| 摘 要： | 针对通常比幅单脉冲接收机中中放自动增益控制系统在信号强度快速变化及脉冲重复频率可变情况下遇到的困难,本文给出了一种新的中放自动增益控制系统.文中首先简要回顾了从时域性能出发进行AGC设计的概念,随后详细介绍了和、差中放与AGC电路的电路实现方法及相应的设计考虑,最后并给出了若干主要指标的测试结果及外场试验的一些结果.

| Abstract: | A system of m.f.amplifiers and the associated AGC loop which is used in amplitude-comparison monopulse receiver is systematically presented, with the purpose of overcoming the difficulty encountered by the conventional system in the situatims where the input signal exhibits rapid changes in average strength and variable pulse repetition rates.After a brief review of the design approach of AGC loop based on the time-domain performance, practical design considerations regarding the implementation of the amplifiers and the AGC ratio circuits are explained in detail Experimental data involving the main characteristics of this system and results of the field investigation are also given. |
