MM-WAVE RADAR VITAL SIGNS DETECTION APPARATUS AND METHOD OF OPERATION

摘要

The present invention discloses mm-wave radar sensor to be applied for detection of the vital signs of humans, particularly babies, as well as animals, in clinical and daily life environments. The key system relevant elements are the utilization of mm-wave integrated radar system, with specific planar high-gain antenna radiation pattern, with separate receive and transmit antennas, and detection of the following biomarkers: heartbeat and respiratory dynamics. The method of operation calculates the probability of a number of possible events. In case that probability is above a predefined threshold, the interaction with end user or end system is initiated, typically by using arbitrary wireless communication. Corresponding event related predefined actions are performed in that case. Preferably, the system is using 60 GHz integrated radar front end working in Doppler operation mode, with 4 x 4 TX and RX planar radiation elements, with physical size typically in the range 4 x 2 x 1 cm, or smaller.
