Doppler Elaboration for Vibrations Detection Using Software Defined Radar

A Doppler elaboration based on a Software Defined Radar (SDRadar) system is proposed in this work as alternative to standard hardware architectures for vibrations detection. An SDRadar prototype, fully realized via software, is implemented to satisfy various frequency detection requirements, even in the presence of slow and small oscillations, by simply changing ‘real time’ the useful parameters (e.g. bandwidth and acquisition time). Experimental validations by a device able to produce a harmonic motion, are discussed to prove the proper detection capabilities of the proposed architecture.
