对于卫星导航系统,由导航天线进行波束合成的多路并行导航信号需要具有严格的相位一致性,本文给出基于专用地检设备的多通道相位一致性测量方法. 该地检设备采用载波相位辅助伪码测距技术,通过载波相位和伪码相位的联合解算,实现了伪码相位对载波相位解整周期模糊,最终测距精度达到1ps. 采用该测试方法对系统进行配相,实现了各通道无周期模糊的相位一致性.

For satellite navigation systems,the multi-channel parallel navigation signals will be syn-thesized by the navigation antenna beam forming system needs to have strict phase consistency. This pa-per presents a multi-channel pseudo range measurement method to measure the relative delay of multi-channel navigation signals based on carrier phase. By the joint calculation method of carrier phase and pseudo code phase, the extremely distance accuracy of 1ps is achieved. And then, the strict phase con-sistency without difference of the carrier cycles is realized.
