Abstract :
Micro-Doppler induced by mechanical vibration or rotation of structures in a radar target is potentially useful for target detection, classification and recognition. While the Doppler frequency induced by the target body is constant, the micro-Doppler due to vibrating or rotating structures of the target is a function of dwell time. Analysis of the time-varying Doppler signature in the joint time-frequency domain can provide useful information for target detection, classification and recognition
