Micro doppler effect induced by non uniform motion of mobile receiver via faraway DTV transmit station was analyzed based on multipath channel propagation characteristics. To accurately separate and extract micro Doppler values of multiple signal components in DTV received signals

the support vector clustering (SVC) algorithm was applied. By using FRFT transform results of the received signal

clustering analysis was conducted

and synchronous detection and accurate estimation of multiple micro doppler components was realized. The simulation results showed that the method proposed can separate

extract and estimate micro doppler values of multiple signal components from different paths and different DTV transmit stations under single frequency network.
