Alarm clock control method based on sleep staging prediction, radar and storage medium

The invention provides an alarm clock control method based on sleep staging prediction, a radar and a storage medium. The method comprises the following steps: acquiring an echo signal obtained by detecting a bed body surface area by a radar in real time, and extracting a human body sleep feature based on the echo signal; calculating corresponding sleep staging indexes according to a preset period based on the human body sleep features; if it is monitored that the current time reaches the timing time of the alarm clock, predicting the sleep staging index of the Mth period after the current period based on the sleep staging indexes of the latest N periods; and determining a ringing scheme of the alarm clock according to the obtained sleep staging index, and controlling the alarm clock to ring based on the ringing scheme. According to the method, sleep staging calculation can be performed on people by adopting a radar detection method, and the sleep staging index of the user at the alarm clock timing time is pr
