Claim 7:
8. The sonar apparatus according to claim 1, wherein the one or more signal waveforms comprise three or more signal waveforms, and
wherein the processor, when executing the program instructions stored in the memory:
selects one or more pairs from among the three or more signal waveforms extracted;
calculates a cross-correlation value between each of the one or more pairs;
obtains one or more target velocities, for the one or more pairs, each of the one or more target velocities being derived based on the peak value and an integrated value of the square of the cross-correlation value between each of the one or more pairs to calculate, as the target velocity, an average value of the one or more target velocities; and
displays the average value of the target velocity for each of the one or more pairs on the display.
