초록
An acoustic echo-sounder is an effective piece of equipment used to detect underwater targets by emitting ultrasonic waves and receiving reflections from the targets. In this study, we present a new compact echo-sounder and implement a new signal processing algorithm to estimate fish populations. Experimental results demonstrate that our device has comparable scattering strength and signal patterns to those of a popular acoustic echo-sounder (Simrad, EK-15). Because our method accurately estimates fish abundance, the method is reliable for making fish-management decisions.
