低频宽带机械滤波器的相位漂移问题

The Phase Shift of Low Frequency Wide -band Mechanical Filter

本文针对机械滤波器（以下简称MF）相位漂移对测控系统精确的影响，介绍MF的技术要求和特点，并着重介绍了控制该MF相位漂移的设计考虑。通过试验实际达到的性能指标，并作了性能分析。

In this paper, considering relative shift of MF on TT&C accuracy, specification and charac treristics of MF is introduced. MF phase shift control design is emphasized. Per formance specification is reached via test and performance is analyzed.
