Synchro-Compensating Chirplet Transform

The novel time-frequency transform, called synchro-compensating chirplet transform, is proposed to represent optimally the overlapping signals in a time-frequency domain. By the control of the self-tuning demodulated operator, an instantaneous rotating operator is introduced in the proposed algorithm to blur the noise and compensate the energy of each component simultaneously. The effectiveness of the method for micro-Doppler signals with a high noise is validated through examples.
