PROBLEM TO BE SOLVED: To provide a bottom sediment determination device capable of precisely grasping the circumstances in which deterioration in reliability of bottom sediment determination occurs.;SOLUTION: A reliability display area 50 of several vertical dots is secured between a display area for an image indicating the results of bottom sediment determination (for example, a graph displaying a calculation result of similarity with each bottom sediment) and an area for displaying an echo image. The reliability is calculated on the basis of a noise level of a receiving signal, for example. Specifically, when the noise level exceeds a first threshold, an alert image 52 is displayed to perform the display of indicating the decrease in reliability.;COPYRIGHT: (C)2011,JPO&INPIT
