Abstract
First 1-sound-line received signals are successively generated from an output signal of a transducer. One is selected from among the generated first 1-sound-line received signals as a 1-sound-line received signal of interest. Second 1-sound-line received signals are selected from among the generated first 1-sound-line received signals. The second 1-sound-line received signals include a 1 -sound-line received signal preceding the 1-sound-line received signal of interest and also a 1-sound-line received signal following the 1-sound-line received signal of interest. The second 1-sound-line received signals are averaged into a mean 1-sound-line received signal which corresponds to an undesired multiple-echo signal. The mean 1-sound-line received signal is subtracted from the 1-sound-line received signal of interest to remove the undesired multiple-echo signal from the 1-sound-line received signal of interest.
