To provide a radar device capable of tracking a target accurately and stably, taking into account the possibility that a plurality of echoes may merge. A radar device is provided with a tracking processing unit, a merging possibility calculating unit and a preliminary handling processing unit. The merging possibility calculating unit calculates an echo merging possibility, which is the possibility that echo merging, whereby a plurality of echoes become integrated, will occur in the future, based on movement information including the position and speed of a target. The preliminary handling processing unit performs an advance handling process, which is a process for handling future occurrences of echo merging, based on the echo merging possibility.

A data processing apparatus is provided, which includes processing circuitry. The processing circuitry is configured to acquire a data set from target detected by a detection apparatus, perform rendering of the data set, and generate a plurality of views arranged on a screen. Each view of the plurality of views includes a plurality of pixels. Each pixel included in the plurality of views is associated with a plurality of pieces of information including a first information displayed on the screen and a second information that indicates a view among the plurality of views to which the pixel belongs.

A ship maneuver supporting device capable of displaying a collision risk zone which matches navigation feel of a ship operator with reduced calculation load, is provided. The ship maneuver supporting device 1 includes processing circuitry (11, 21, 31, 41). The processing circuitry calculates a collision risk value for determining whether a collision risk zone that is a zone where a possibility of a collision between a first ship and a second ship will occur in the future is high is to be displayed, based on a separating distance between the position of the second ship estimated at a plurality of future time points and the position of the first ship estimated corresponding thereto, in consideration of a physical size of at least one of the first ship and the second ship. Further, the processing circuitry generate display data for displaying the collision risk zone at the estimated position of the second ship, based on the determination using the collision risk value.

Techniques are disclosed for systems and methods to provide visually correlated radar imagery for mobile structures. A visually correlated radar imagery system includes a radar system, an imaging device, and a logic device configured to communicate with the radar system and imaging device. The radar system is adapted to be mounted to a mobile structure, and the imaging device may include an imager position and/or orientation sensor (IPOS). The logic device is configured to determine a horizontal field of view (FOV) of image data captured by the imaging device and to render radar data that is visually or spatially correlated to the image data based, at least in part, on the determined horizontal FOV. Subsequent user input and/or the sonar data may be used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.

The present disclosure relates to a system and a method for monitoring vessel traffic information. The system for monitoring vessel traffic information includes: an interlock device configure to adjust identification information of a wireless terminal included in a received message to correspond to an identification system of auto identification system (AIS) message and convert the received message into a AIS message type, when receiving a message including ship information from a wireless terminal of a ship located in at least one ship network; a merging device configure to merge the ship information included in the converted AIS message with radar image information; and a monitoring device configure to display merged monitoring information on a monitoring screen.

To accurately calculate a location range which a ship is capable of reaching within a prescribed time interval. A signal processing device is configured so as to be equipped with reachable range calculation units 17, 18 which calculate a reachable range, which is the location range a ship is capable of reaching within a prescribed time interval, on the basis of the static information of the ship.

An aircraft display system to present a real-time, three-dimensional depiction of a region around an aircraft, where this three-dimensional depiction is fixed to the aircraft's coordinate location and attitude. As the aircraft moves in attitude (e.g. roll, pitch, or yaw), in altitude (e.g., climbing and descending), and/or laterally, the three-dimensional depiction tilts and moves with the aircraft. The display may include a three-dimensional volumetric representation that may identify and prioritize hazards in the region around the aircraft. The aircraft display system may combine data from a plurality of sensors into a composite, real-time, three-dimensional synthetic vision display that determines a priority for each hazard.

Methods and computer-readable media are described herein for providing an automated validation of vehicle positioning and corresponding error notification. According to various aspects, a first position of a vehicle may be determined using a first positioning system. A second position of the vehicle may be determined using a second positioning system. An offset between the first and second positions of the vehicle may be determined. If the offset exceeds a threshold offset, a notification may be provided to indicate a potential error in the position of the vehicle.
