A Radar Scope on the Arduino UNO Q: Multi-Target Tracking with the Ai-Thinker RD-03D mmWave Sensor

UNO Q with a 24 GHz radar wired to the board to build a live radar scope - the MCU turns a binary sensor stream into three tracked targets, and the Linux side draws them sweeping across a web dashboard. Along the way, a proper look at how FMCW radar works, all showing the strength of mmWave radar.
