基于测控基带备机的防错锁方法改进

Improved Method of Preventing Mislock Based on Measuring and Controlling Baseband Backup Machine

为了解决测控基带备机双向捕获过程中错锁的问题,对接收机载波锁定原理、频率捕获单元工作流程进行分析,查找产生错锁原因。搭建模拟测试环境开展试验验证,并对软硬件进行适应性修改,改进了防错锁方法,为测控活动提供有力保障。

In order to solve the problem of mislock in the bidirectional capture process of TT&C baseband backup machine,the carrier locking principle and frequency capture unit working flow of receiver are analyzed and the reason of mislock is found.Build a simulation test environment to carry out test verification,modify the software and hardware adaptively,improve the method of preventing mislock,and provide a strong guarantee for measurement and control activities.
