短期频率稳定度对多普勒误差的影响

EFFECT OF SHORT-TERM FREQUENCY STABILITY ON DOPPLER ERROR

本文讨论本振短期频率不稳引入的多普勒测速误差。导出了均方根速度误差与本振短期频率稳定度之间的关系。并给出了实验测量结果。

The reasons that induce the measuring error in Doppler measuring velocity systems are discussed and specially the effect of short-term frequency stability of local oscil lator on measuring velocity error is analyzed. The relationship between root mean square velocity error and short-term frequency stability of local oscillator is obtained. Finally,expcri mental results are given.
