Study on the clutter filter of color Doppler processor

Discriminating the clutter signal from Doppler signal is the main function of CDP(color Doppler processor). Up to now, a general method of eliminating clutter signal is using IIR high pass filter. There are many filters that were introduced in other paper. In this paper, we propose the new method of filtering clutter signal. To the new method, we adopt an appropriate filter that can eliminate clutter filter most effectively.
