An X band low cost, simple and compact continuous wave Doppler radar is presented. The whole front end is designed using hybrid microwave integrated circuits (mic).
We report the Doppler shift of Na spectroscopy changing with the slow wave factor in a slow wave microwave field the reason of the phenomenon is discussed.
报道了在慢波场中原子波谱多普勒频移随微波慢波系数的变化，并讨论产生这种现象的原因。

The doppler signal that is mixed and exported by microwave interferometer is a non-stationary signal, its instantaneous frequency is changing time variant.
