| Abstract(in English) | This study addresses the issue of super-resolution pulse compression technique (PCT) used for ultrasound imaging. Time resolution of multiple ultrasonic echoes using the FM-Chirp PCT is limited by the bandwidth of the sweep-frequency: the resolution depends on the sharpness of the auto-correlation function. The PCT resolution is insufficient when multiple scatterers are in close formation. Herein, we propose the Super resolution FM-Chirp correlation Method (SCM) and evaluate its performance. This method is based on the MUSIC (MUltiple SIgnal Classification) algorithm. Our simulations were made for the model assuming multiple signals reflected from some scatterers. We confirmed that SCM detects the time delay of complicated reflected signals with high resolution. |
