摘　　要：统一测控系统接收机采取了一定的方法防止伪码捕获跟踪环和载波锁相环错锁,但是在航天器测控过程中,错锁仍然发生。通过分析伪码捕获跟踪环和载波锁相环错锁的原因,提出对错锁的智能识别方法和自主处理措施,以增强系统工作的可靠性,提高扩频统一测控系统的测控成功率。False-lock of receivers occurs sometimes in the process of TT&C although avoidance measures are taken.Intelligent recognition and handling of TT&C system receiver false-lock are proposed based on analysis of the reasons of false lock of pseudo-code loop and phase-locked loop in order to improve equipment reliability and increase TT&C success rate.
