PROBLEM TO BE SOLVED: To select a sensor, among a plurality of acoustic sensors for receiving an output sound from an underwater target (underwater mobile entity) M, which is close in distance to the underwater target M and quickly display the selected sensor on a main screen.SOLUTION: Conventionally, a sub-screen is called up to a main screen of a display unit 2 and channel information pertaining to each of a plurality of acoustic sensors P1 to P5 is displayed on the sub-screen. In this case, there is inconvenience that a portion of the displayed information on the main screen is blocked by the sub-screen. In the present invention, on the other hand, the distance between an underwater target (underwater mobile entity) M and each of the acoustic sensors is calculated by a data arithmetic processing unit 11, and a data display control unit 12 applies a priority sequence for display to each of the corresponding acoustic sensors in order of increasing size of the calculated distance data, and channel information pertaining to some of high-priority acoustic sensors is displayed on the main screen in the order of this priority sequence without providing a sub-screen.SELECTED DRAWING: Figure 1 |
