摘　　要：介绍航天测控通信系统中首区测控站微波接收大动态控制的实现方法,采用"二状态"断续自动控制方案和高性能大动态控制模块,达到96dB的大动态控制,实现了抗强信号互调、高灵敏度接收及和、差通道相位、增益的高一致性。The realization of microwave large dynamic range control for the first zone TT&C station in manned space flight TT&C and communication system is introduced. Adopting the 'two states' intermittent and automatic control scheme and using high performance large dynamic range control modules, 96 dB large dynamic range control is achieved, as well as anti-strong-signal- intermodulation,high sensitivity receiving and the consistency between the phase and gain of sum and difference channels.
