Respiratory activity is an important parameter for observation of human body activity. A normal adult has a respiratory rate of 12-15 breaths/min in normal conditions. Breath sensor based on non-contact Doppler detector allows for the measurement and detection and the absence of the breathing action, which may cause death in a few minutes. The monitoring and detection of some respiratory abnormality presents interest in certain situations (i.e. patients from intensive therapy, of newborn childre
