    • A screen on which water depth information obtained from an echo signal is historically displayed and a screen on which fish school detection information obtained from an echo signal is displayed, are displayed side by side on a display screen of a display instrument or either one is displayed by switching. Thus, a large amount of information is displayed on a limited space of a small display instrument efficiently and effectively and to be easy to see. Further, when a water depth value becomes a set value of an alarm water depth mark or less, an alarm is displayed on the display screen of the display instrument, and an alarm is given by sound. At the same time as this, the brilliance of the display screen is raised to the maximum brilliance to make the screen brighter, so that the contents of the alarm are made easy to see. Thus, quick measures can be taken in an emergency. Moreover, after a mode is set to a help mode by a mode switch, when any one of keys in an operation portion is pushed, guidance of the function, operation procedure, and the like of the pushed key is displayed on a display portion. Thus, the guidance as to the key can be displayed by a simple operation in a help mode.
    • 历史上显示从回波信号获得的水深信息的屏幕和显示从回波信号获得的鱼学校检测信息的屏幕并排地显示在显示器具的显示屏幕上或者显示 通过切换。 因此,在小型显示装置的有限空间中有效且高效地显示大量的信息并且易于看见。 此外,当水深值成为报警水深标记的设定值以下时,在显示装置的显示画面上显示报警,并且通过声音给出报警。 与此同时,显示屏的亮度提高到最大的亮度,使屏幕更亮,使报警的内容变得容易看清。 因此,在紧急情况下可以采取快速措施。 此外,在通过模式切换将模式设置为帮助模式之后,当按下操作部中的任何一个键时,在显示部分上显示所推动的键的功能,操作过程等的引导。 因此,可以通过在帮助模式中的简单操作来显示关于键的指导。

    • An underwater detection system for displaying underwater conditions over a large area around a ship comprises a linear array type transducer, a transducer training mechanism for rotating the transducer stepwise in a horizontal plane, a receiver which forms a receiving beam for scanning a fan-like vertical cross-sectional area by giving specified time delays or phase differences to echo signals received by the transducer, an image memory for storing echo signal data picked up by the receiving beam in addresses defined by horizontal directions relative to the ship and depths, a sampling circuit for reading out data of one vertical line after another in a downward direction from the image memory and determining a bottom depth in each vertical line, a seabed data memory for storing bottom depths, a PPI image generator for producing a fractional PPI image depicting the bottom based on bottom depth data read from the seabed data memory, and an indicator for presenting search results in the form of a plan view covering a large area of search around the ship by jointly displaying fractional PPI images produced by the PPI image generator.
