K-Nav Radar

The radar display unit is a type-approved radar /

ARPA on which approved nautical charts can be

displayed as an underlay to the radar video.

Raw data from the antenna is processed in the display

unit, which means that filtering is applied locally

according to the operator’s requirements. The display

unit tracks its own targets and also displays AIS

targets. If radar and AIS targets duplicate each other,

they are ”associated”: the system replaces them with

a single new target (and identifier). This ensures that

the operator cannot mistake a single ship detected by

both radar and AIS for two vessels.

To enhance radar performance and avoid blind

sectors, video from up to four radars can be displayed

simultaneously in a composite radar picture. The

system automatically tracks targets across boundaries

between the sectors covered by each radar.
