Millimeter wave radar and intelligent bed linkage attitude control method and system

The invention provides a millimeter-wave radar and intelligent bed linkage attitude control method and system, and relates to the millimeter-wave radar technology, and the method comprises the steps: obtaining the echo information of a millimeter-wave radar reflected by a target object located on an intelligent bed, carrying out the filtering of the echo information, carrying out the phase unwrapping of the filtered echo information, and carrying out the phase unwrapping of the filtered echo information, obtaining target phase information of the target object; heartbeat information and breathing information of the target object are extracted from the target phase information, and heartbeat features are extracted from the heartbeat information and breathing features are extracted from the breathing information through an adaptive filter in combination with an adaptive signal processing method; and according to the heartbeat features and the breathing features, determining a sleep sign state of the target objec
