Radar video mosaicking
Essential for clear traffic images
Multiple radar coverage of busy fairways offers many advantages such as higher availability and superior false track suppression. At the same time, care must be taken not to clutter the traffic display with overlapping radar video, especially when the distance between radar stations is large.
To prevent double presentation in the radar image our solutions make use of a technique called mosaicking. With this feature we provide the operator with a maximum overview of the traffic image, without unnecessary overlap of the image from individual radars.
How it works
Inherent to the operating principle of a radar, the further away a vessel is, the more spread out the radar echoes become. This is why we clip the image from the radar in the middle of the overlap, so that the nearest and most accurate radar echoes are shown. A mosaic defines in which areas video must be shown from which radars.
The operator can select a number of individual radars for display of the radar video. The selected radars can be part of the selected mosaic or additional to the mosaic. This can be done for any number and any combination of radars.
Mosaicking is a display function and only affects the video an operator sees. All of the radar coverage of the waterway is used for target tracking, and in fact greatly enhances the quality of the tracking.
Note the difference in video quality. The radar video from the nearby radar shows much more detail and is therefore best suited for display.
