摘　　要：文中从AGC回路的调整过程在有限时间内结束这一条件出发来寻求PRS的AGC回路参数,并推导出了AGC系统的环路增益稳定条件,进而得到了受控放大器的增益控制特性。根据所得的增益控制特性的特点选择了差分放大器并加以实现。The automatic gain control（AGC） loop＇s parameters in the passive radar seeker（PRS） were sought from the condition that its adjustment process ends in limited time, the stable conditions of the AGC loop＇s gain and gain control character of a controlled amplifier were obtained. According to its character, a differential amplifier was chosen and made into reality.
