Abstract

The purpose is to provide an underwater detection device (10) and an underwater detection image generation method capable of properly displaying a bottom and visually recognizing the states of the bottom and a target. The underwater detection device (10) includes a bottom detection module (17a) that detects a bottom position based on an echo data indicating a signal intensity of a reflected wave, an edge calculation module (17b) that calculates an edge position of a bottom echo with respect the bottom position, a correction module (17d) that calculates a correction data in a range from a transmission position to the bottom position based on the echo data between the transmission position and the edge position, and an image generation module (17e) that generates a detection image in a display mode corresponding to the signal intensity of the correction data and a bottom image in a display mode different from the detection image based on the bottom position.
