Can radar detect heartbeat?

Radar sensors are used for the detection of sub-millimeter movements of chest wall skin surface that occur due to heartbeats, whereas various signal processing methods are employed for heart rate extraction from discretized radar signals.

What is UWB radar used for?

UWB radars used are able to identify the posture and motion changes of a person, and also to measure human vital signs.

What sensor can detect heartbeat?

The infrared sensor is responsible for sending infrared light to the body. This sensor has a pair of transmitter and receiver. Using photodiode can also detect reflective light from the body and this signal is sent to the microcontroller to detect heartbeat.

What is UWB radar?

Ultra-wideband (UWB, ultra wideband, ultra-wide band and ultraband) is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. UWB has traditional applications in non-cooperative radar imaging.
