    摘要:

    在航天测控系统中,校相是日常设备维护必不可少的手段之一。通常情况下,校相的相位修正值是运用软件无线电的方法计算而得。矢量电压表是一种能同时测量信号幅度和相位的仪器,具有精度高、频带宽、灵敏度高的特点。利用矢量电压表测量和差通道相位差,计算出相位修正值,在硬件设备上实现了相位快速校准。该技术已在工程中成功实现。

    Abstract:

    Phase calibration is an essential means for daily equipment maintenance in space tracking, telemetry, command(TT&C) system. Generally phasecorrected value of the phase calibration is analyzed through applying software defined radio(SDR).Vector voltmeter is an advanced instrumentation with highprecision, wide band and high sensitivity, which can test amplitude and phase simultaneously. The phase difference of sumdifferential channel is calculated by using vector voltmeter. A novel phase calibration method is realized under the hardware platform. The technique discussed in this paper has been successfully applied in project.
