2.3.1 Operation

The IWR6843 is loaded with a flashed image that, when booted and initialized, receives a chirp configuration specified using the area scanner visualizer. In the area scanner visualizer, the location and dimension of the zones to monitor are set as well as other visualization properties. Then, using the visualizer, the chirp configuration is loaded and sent to the sensor to start monitoring the area of interest for zone occupancy.

The strongest reflections reported by the radar device are reported as detected objects to the host PC through the UART. The detected objects collectively form a point cloud representation of the scene as seen by the sensor. If an object generates a point cloud of at least 15 points within an area, the area is considered breached and the visualizer updates to highlight the occupied area.
