Finding Shift in frequency when reflected from a solid object

[user11422]

Hi, I've started working with the BladeRF xA9. Initially, I managed to transmit a signal and receive it when it gets reflected from a stationary target. I was wondering if I start vibrating the target to and fro will I be able to get any changes in my plots? I actually want to find the doppler shift from the BladeRF when I vibrate the target with say 1-2Hz. If someone could suggest any other method which I can adapt to find the Doppler shift using the BladeRF please tell me as it would be very helpful.
