Product introduction
1.1 Product introduction
The R24DVD1 radar module employs the millimeter-wave radar technology to realize distance and speed sensing
of human motion. Based on the 1T1R FMCW (frequency modulated continuous wave) signal processing
mechanism, this module performs wireless sensing on the status of people in the specific area via the synchronous
sensing technology that detects motion intensity and chest expansion parameters.

1.2 Theory of operation
The radar antenna transmits electromagnetic wave signals, and synchronically receives reflected echo signals. Then,
the radar analyzes the waveform parameter of the echo signals, and gives feedback on distance, orientation, speed
and other information of the target, making it possible to detect the status and trajectory of moving objects.
