SYSTEM AND METHOD FOR RADAR GESTURE RECOGNITION

A method for gesture recognition includes receiving, by a processor, a first digital intermediate frequency (IF) signal stream from a first receive antenna and receiving, by the processor, a second digital IF signal stream from a second receive antenna. The method also includes computing, by the pro...

Beschreibung
Zusammenfassung:	A method for gesture recognition includes receiving, by a processor, a first digital intermediate frequency (IF) signal stream from a first receive antenna and receiving, by the processor, a second digital IF signal stream from a second receive antenna. The method also includes computing, by the processor, a weighted Doppler metric stream based on the first digital IF signal stream and the second digital IF signal stream and computing, by the processor, an angle metric stream based on the first digital IF signal stream and the second digital IF signal stream. Additionally, the method includes computing, by the processor, a correlation between the weighted Doppler metric stream and the angle metric stream, to generate a first correlation and recognizing, by the processor, a gesture, based on the first correlation.
