The Navtech Radar SDK provides a simple interface to communicate with Radar sensors. As well as ROS and ROS2 examples, the SDK includes source code for C++, a simple .NET DLL that can easily be integrated into applications running on Windows and Linux.
The IA sensor operates in two modes, native data and plot extractionNavtech Radar sensors provide output in one or both of two modes: “FFT data” (sometimes referred to as “raw radar data” and “navigation output”. These are explained below. The SDK provides support for both modes, allowing developers to receive either type of data from the sensor and also send control messages back.
Communication between the sensor and the software is over Ethernet and utilises a proprietary binary communication protocol called Colossus Network Protocol. The SDK abstracts this protocol to avoid having to develop the low level socket and messaging processing code. However you can develop your own interface without the SDK if required and the protocol documentationColossus Network Data Protocolwill provide all the information you need to achieve this.

In this mode the radar outputs FFT processed data, which is amplitude and range. Data is sampled 400x per radar rotation and packet is sent across the network for each sample. This packet includes the sample azimuth enabling the receiver to analyse target data based on range, bearing and amplitude. The data output rate for native mode is quite high. The normal data rate is between 11Mbps - 38Mbps.
