What is the radar detects?
The radar can detect tiny, repeated movements from the baby's chest and abdomen caused by breathing and heartbeat-related micro-motion. It is not directly “seeing” the heartbeat on video.
How detection is performed?
The radar sends out low-power mmWave signals and receives the reflected signal from the body. Tiny body movements change the returned signal, and the algorithm estimates breathing and heart-rate trends from those changes.
What is the detection difference between mmWave Radar and camera?
The camera depends on the optical image. The radar depends on its radio-wave sensing area. These two areas can overlap, but they are not always identical.
