Doppler Sensor with CDM324 24.125GHz Module and STM32f303Disco

Introduction I got some CDM324 24.125GHz doppler module last year, and decided to modify it to detect object speed. Despite its complexity to design, CDM324 module has been made incredibly cheap. It basically comprised of a TX antenna, a RX antenna, resonator as frequency source, some power divider and mixer all in a tiny two-layer […]
