Abstract
A device for analysis of sleep time using a radar includes a transceiver configured to transmit a radar signal toward a subject and receive the radar signal reflected from the subject; a breathing signal collection unit configured to collect a breathing signal of the subject based on the radar signal; a first sleep time detection unit configured to detect a first sleep time of the subject from the breathing signal based on a presence discriminator; a second sleep time detection unit configured to detect a second sleep time of the subject based on a probability value of the first sleep time; and a final sleep time determination unit configured to determine a final sleep time of the subject based on the second sleep time.
