An apparatus for remote contactless monitoring of sleep apnea, comprising a radar transmitter having a transmitting antenna for radiation of radio frequency signal towards a human body, and a radar receiver for receiving a signal reflected from the human body. The radar receiver comprises a receiving antenna positioned at a predefined distance from the transmitting antenna. The apparatus further comprises an accelerometer adapted to be placed on a human body, a microphone and a signal processor. Respective outputs of the radar receiver, accelerometer and microphone are connected to the input of the signal processor which is configured for extracting and processing apnea-specific physiological parameters of the at least one human body from the inputted signals of the receiver, accelerometer, and microphone.
