The investigation of clutter suppression for color flow map
Jia-Chen Ma, Yi Shen, SU Bao-ku · 2004
Based on analyzing the current typical method to suppress clutter for color flow map, a new structure is proposed. It uses a second-order AR model to calculate the mean frequency and covariance of Doppler signal, and uses a time-domain self-adaptive regression filter to deal with the correctional echo. And the simulation with simulated data is done to verify the correctness and superiority.
