摘要
介绍了扩频测控系统中非相干伪码测距的原理,针对航天测量船在海上校飞过程中出现的非相干伪码测距跳值问题进行了分析与研究,并从测量船测控设备软件和参数设置等方面提出了解决措施。
The basic principle of non -coherent PN ranging in spread spectrum TT&C systems is introduced. Then, exceptional range data in non -coherent PN ranging, which happened when the tracking ship was taking flight test, is analyzed. Finally, a solution scheme, involving software and parameter optimization, is presented.
