Systems and methods for determining presence and/or physiological motion of at least one subject using a Doppler radar system are provided. In one example, the apparatus includes at least two inputs for receiving a transmitted signal (e.g., a continuous wave signal), the transmitted signal modulated during reflection from at least one subject, and logic (e.g., hardware, software, and/or firmware; including digital and/or analog logic) for determining physiological motion associated with the at least one subject (e.g., a heart rate and/or respiration rate of the subject). In one example the logic includes comparing (e.g., mixing) the received signal with the source signal. The apparatus may further comprise logic for quadrature detection of the received signals, and may include various blind source separation algorithms for detecting signals associated with separate subjects.
