<P>PROBLEM TO BE SOLVED: To provide an underwater detection device, an underwater detection method and a program capable of acquiring a reliable depth even when an echo signal with a predetermined level or higher is not available. <P>SOLUTION: An underwater detection device which detects a water depth on the basis of an echo signal generated when a transmitted signal is reflected under water: acquires a position of an own device as well as water depth data indicating the water depth at the position; estimates the water depth to be detected on the basis of the acquired position as well as the water depth data; and displays an image based on the echo signal as well as the estimated water depth. <P>COPYRIGHT: (C)2013,JPO&INPIT |
