Abstract

Monitoring vibrations induced on non-rotational components, of a machine is a key requirement to ensure that the machine is well within safe operational limits. Existing approaches are sensor based and may not be practical in many practical scenarios with extreme environments. Embodiments herein provide method and system for monitoring machine health using radar based segregation for induced machine vibrations. The method provides model free a data driven approach wherein a micro Doppler signal captured by the RADAR placed in proximity of a target machine is processed and analyzed in accordance with a Wide Band Frequency Spectrum (WBFS) to estimate a rotational frequency and a translational frequency of induced machine vibrations in the target machine. Further, apply a rule engine on the estimated rotational frequency and the translational frequency to provide an alert notification to an end user when the induced machine vibrations cross the defined machine standards.
