摘要:
PURPOSE:To extract Doppler echoes without being masked by reverberation even if S/R ratio is poor. CONSTITUTION:An optimum AGC for reverberation characteristic is performed for each frequency and convergence time can be reduced by loading a value corresponding to the reverberation characteristics for each frequency from a ROM 15 as the initial value of an AGC (Auto Gain Control) circuit 6, thus extracting Doppler echoes without being masked by reverberation owing to the reverberation suppression effect.
