Abstract
A fish sonar is capable of detecting ultrasonic waves from a desired direction by shaping the waveforms of the outputs of a pair of vibrators spaced apart by a certain distance, and detecting a delay of the output from one of the vibrators with respect to that of the other of the vibrators so as to detect the direction of the ultrasonic waves coming to the pair of vibrators and to delay the output of the other of the vibrators with respect to the output of one of the vibrators.
