Radar signal distribution

K-Nav Radar uses a high-speed network for collecting

radar signals at the transceiver and distributing

them to the display unit: a radar interface (RIN) unit

converts analog radar signals to digital signals at the

antenna location and sends them to the display unit

over the network. Processing of the video, including

target tracking, is performed locally by the display

unit, and filtering is also applied locally to give the

operator full control over the displayed picture.

Optional interswitching capabilities are available to

allow different display units to access radar data from

any antenna over the network. This option provides

fault tolerance with respect to signal processing.

To enhance radar performance and avoid blind

sectors, an additional option permits video from

up to four radars to be displayed simultaneously

in a composite radar picture. In such a composite

picture, targets are automatically tracked across the

boundaries between the sectors from each radar.
