    摘要: Systems and methods for detecting presence and/or physiological motion of at least one subject using a Doppler radar system and determining a number of subjects within range are provided. In one example, the apparatus includes a receiver for receiving a transmitted source signal, the transmitted source signal modulated by at least one subject, logic for mixing the received transmitted signal and a local oscillator signal, and logic for performing a Generalized Likelihood Ratio Test (GLRT) on the mixed signal to determine a number of subjects modulating the signal. Additionally, the receiver may include a quadrature receiver operable for mixing the source signal and the received modulated source signal to generate in-phase (I) and quadrature (Q) data, whereby nulls in the signal are avoided.

    摘要: Systems and methods for determining presence and/or physiological motion of at least one subject using a Doppler radar system having a quadrature receiver are provided. In one example, the apparatus includes a transmitter for transmitting a source signal, a quadrature receiver for receiving the source signal and a modulated source signal (e.g., as reflected from one or more subjects), and logic for mixing the source signal and the received modulated source signal to generate in-phase (I) and quadrature (Q) data, whereby nulls in the signal are avoided. In one example, the quadrature receiver further includes logic for center tracking quadrature demodulation. The apparatus may further include logic for determining physiological motion (e.g., heart rate and/or respiration rate of a person) of a subject based on the source signal and the modulated source signal.

    摘要: In the non-invasive measuring system, a wireless communication device or other sensing device, gathers Doppler information from signals transmitted by the wireless communication or sensing device and reflected off of a target subject. The gathered information is transferred, preferably, over the existing communication network infra-structure to a presentation device. By placing a body sensor on the target subject, the return of the signal reflected from the subject is enhanced and/or additional information is modulated onto the return signal.

    摘要: 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.
