Point Data
We use Nav Navigation Mode or Point Cloud methods CA-CFAR Mode to extract significant features in the radar data. A threshold is applied to the data and any feature or target which exceeds this threshold is reported as a data point. This data point includes the range, bearing and it's amplitude. Both modes provide all the detected points per azimuth in a single network message. The number of points reported is constrained for performance reasons.
Nav Navigation Mode differs from Point Cloud CA-CFAR Mode because it uses a sub-resolving technique to significantly improve the range calculation for each point. When the radar is operating in its highest resolution this can lead to sub 2cm accuracy.
The Nav Navigation Mode uses a configurable fixed threshold to identify targets however the Point Cloud CA-CFAR Mode has the advantage of using a dynamic threshold based on cell averaging.
Output Format: Select the Navigation Output Format. The Point CA-CFAR Mode output is an alternative to the standard Nav Navigation Mode output.
Nav Navigation Mode: This is the default setting. Nav mode outputs data over TCP/IP to the client. Fore more information about Nav Points please see: https://navtechradar.atlassian.net/wiki/spaces/PROD/pages/2261516289/TCP+Networking#Navigation-Data-Message.
Point Cloud:Point Cloud CA-CFAR Mode:This mode outputs data over UDP. Please refer to: https://navtechradar.atlassian.net/wiki/spaces/PROD/pages/2229239935/UDP+Networking#Point-Cloud-Data for more information about Point Cloud data.
