An image generating device for a radar includes a receiving module configured to receive a radar signal from an antenna and process the radar signal to generate an echo, an edge image generator configured to generate an edge echo image based on the echo acquired at a first time instance, a projected image generator configured to generate a projected echo image based on the echo acquired at a second time instance, and a superimposition generator configured to superimpose the edge echo image on the projected echo image based on the first and second time instances, to generate a superimposed echo image.

Methods and apparatus for providing realtime, 3D visualization of radar system functionality. A visualization system can receive information from a radar system, such as radar commands and radar parameters. After extracting data from the commands and/or parameters, the visualization system generates a three-dimensional (3D), realtime display showing a field of view (FOV) of radar operations including representations of beams generated by the radar system and targets tracked by the radar system.

The purpose is to provide a radar apparatus which can create and display only necessary trail data. The radar apparatus may include an acquisition module, an echo data creation module, a memory, a trail data creation module, and a display unit. The acquisition module may acquire an echo based on a reflected wave from a target object, of a transmitted electromagnetic wave. The echo data creation module may create, based on the echo, echo data at least indicative of a position of the target object. The memory may store determination data set, for every given display area, whether trail data indicative of a moving trail of the target object is to be newly created based on the echo. The trail data creation module may create the trail data based on the echo and the determination data. The display unit may display the echo data and the trail data.

An echo image generating device may be provided, which includes a signal acquiring module, a sensitivity setting module, and a screen generating module. The signal acquiring module may acquire an echo signal from a target object around a ship. The sensitivity setting module may perform a first sensitivity setting for the echo signal in a first range, and a second sensitivity setting for the echo signal in a second range without including the first range, the second sensitivity setting being different from the first sensitivity setting. The screen generating module may generate an echo image of the first range based on the first sensitivity setting, and generate an echo image of the second range based on the second sensitivity setting.

A method for installing a radio wave sensor configured to radiate a radio wave to a range including a target area that is set for detection of an object. The method includes: a step of installing a reference object; and a step of adjusting a radio wave radiation direction of the radio wave sensor, using the reference object as a reference. The reference object is installed at a first position outside the target area.

A target object tracking device is provided. The device includes a memory for storing association information in which a selecting order of target objects is associated with symbols indicating the target objects, respectively, a starting selection accepting module for accepting a selection of the target objects to start tracking thereof, a symbol reading module for reading the symbols for the selected target objects corresponding to the selecting order of the target objects based on the association information, a tracking module for tracking the selected target objects, a symbol displaying module for displaying the symbols read by the symbol reading module, at positions where the target objects tracked by the tracking module are displayed, and a symbol changing module for changing, according to an operation of a user, the association information and displaying the symbols at the positions where the target objects are displayed, based on the changed association information.
