Figure 7
On the far left, a rounded rectangular text box reads, “m m Wave Front End”. Below this box, smaller text reads, “B S S Firmware”. A right-pointing arrow from the “m m Wave Front End” box leads to a larger rectangular container. Inside the large rectangular container, arranged horizontally from left to right, are six rounded rectangular boxes connected by right-pointing arrows. Centered beneath this container is the text, “D S S”. The first rounded rectangular box inside the container reads, “Radar Data Capture”. A right-pointing arrow leads from this box to the second rounded rectangular box, which reads, “first dimension F F T”. A right-pointing arrow leads from the “first dimension F F T” box to the third rounded rectangular box, which reads, “second dimension F F T”. A right-pointing arrow leads from the “second dimension F F T” box to the fourth rounded rectangular box, which reads, “Object Detection (C F A R)”. A right-pointing arrow leads from the “Object Detection (C F A R)”, box to the fifth rounded rectangular box, which reads, “Direction of Arrival Estimation”. On the right side of the diagram, a right-pointing arrow leads from the large rectangular container to a rounded rectangular text box that reads, “Send out detected object data to U A R T port”. Below this rightmost box, smaller text reads, “M S S”.Signal processing chain. Source:https://www.ti.com/tool/IWR1642BOOST?keyMatch=&tisearch=search-everything&usecase=hardware
