A ship vicinity information display device is provided, which is capable of displaying a position etc. of a destination of another ship based on information of the destination obtained from the other ship, in a mode which is intuitively easy to understand. A radar indicator may include a display unit, an AIS interface, and processing circuitry. The display unit may be capable of displaying an image of a situation in the vicinity of one ship. The AIS interface may receive the information of the destination of the other ship. The processing circuitry may acquire a longitude and latitude of the destination based on the destination information of the other ship and graphically display at least one of the position of the destination of the other ship and a direction of the destination from the other ship (other-ship destination symbol), on the display unit.

Ship vicinity information display device and method of displaying information of vicinity of ship

There is provided an echo display device that is easy to manipulate and allows echoes that appear on an echo screen to be designated easily, quickly, and reliably with a cursor. An information display device includes a display componenta track ball, and a controller. The display componentdisplays a radar image in real time based on echo information inputted from a radar antenna. The track ball is manipulated to move a cursordisplayed in the radar image. The controller includes a cursor display position determination component, and this cursor display position determination component determines the display position of the cursorin the radar image based on manipulation of the track ball. Also, when the display position of an echo E1 is within a specific range from a cursor display position (position P2) after the cursorhas moved by manipulation of the track ball, the cursor display position determination component moves the display position of the cursorto a position P3 that coincides with this echo E1.

A ship perimeter information display device is provided. The device includes a sensor information input unit connected with a sensor equipped in a first ship and for receiving an input of a detection result of the sensor, an AIS information input unit for receiving an input of VDO information that is a VHF data link own-ship message contained in AIS information transmitted from the first ship to a second ship, a display unit for displaying a situational image illustrating a situation around the first ship, and a control unit for displaying, on the display unit, information indicating a difference between first state information of the first ship obtained based on the detection result of the sensor and second state information of the first ship obtained based on the VDO information.

Device and method for displaying ship perimeter information

A radar device includes an antenna, from which a detection signal is transmitted while the antenna being rotated and by which a reflective wave of the transmitted detection signal is received to detect echo data, wherein image data is generated based on the detected echo data, a continuity detecting module for detecting a planar continuity of the currently detected echo data with respect to a pixel concerned in the image data, a behavior data generating module for generating behavior data indicative of a behavior of the echo data for a predetermined number of scans of the past in the pixel concerned based on behavior determination data, and an echo kind determining module for determining a kind of the echo data of the pixel concerned based on the planar continuity and the behavior data.

Radar device and echo data processing device

An onboard equipment network system comprises a radar core device, a GPS core device, an echo sounder core device and a sonar core device and display devices which are connected to a network through a hub. Each core device includes a detecting section or a positioning section, as well as a control section, a power supply section and a data transmitter for transmitting detecting signals or positioning signals, while each display device includes a command section for transmitting command data to the individual core devices for setting their operating conditions and a display section for displaying image data received from the individual core devices. The command data is transmitted using Transmission Control Protocol (TCP) while the image data is transmitted using User Datagram Protocol (UDP).

Network system for onboard equipment

A forward-looking sonar includes a transducer array which is divided into a first sub array and a second sub array, a first beamforming section for forming a first receiving beam with the first sub array, and a second beamforming section for forming a second receiving beam with the second sub array. The forward-looking sonar receives target echoes from a wide sounding area with these receiving beams. The forward-looking sonar further includes a position measurement section for determining the position of a target based on the direction of the target calculated from a phase difference between the echoes from the target received by the first and second receiving beams by a split-beam method and the distance to the target calculated from time needed for receiving the echoes after transmission.
