Abstract
An underwater detection apparatus is provided. The underwater detection apparatus includes a transmitter, a receiver, and a hardware processor. The transmitter transmits a transmission wave. The receiver obtains a receive signal based on a reflection of the transmission wave. The hardware processor is programmed to at least detect an underwater target object based at least in part on the receive signal, estimate a density index value of objects within a given area in a vicinity of the underwater target object, and calculate a size index value of the underwater target object based at least in part on the density index value and a target object signal intensity representing a maximum intensity of the receive signal corresponding to the underwater target object.
