A vibration sensor based on the use of a Software-Defined Radio (SDR) platform isadopted in this work to provide a contactless and multipurpose solution for low-cost real-timevibrations monitoring. In order to test the vibration detection ability of the proposed non-contactmethod, a 1 GHz Doppler radar sensor is simulated and successfully assessed on targets at variousdistances, with various oscillation frequencies and amplitudes.
