摘要： A method and system for cancelling body movement effect for non-contact vital sign detection is described. The method begins with sending on a first electromagnetic wave transceiver a first electromagnetic signal with a first frequency to a first side of a body, such as a person or animal. Simultaneously using a second electromagnetic wave transceiver a second electromagnetic signal is sent with a second frequency to a second side of a body, wherein the first frequency and the second frequency are different frequencies. A first reflected electromagnetic signal reflected back in response to the first electromagnetic wave on the first transceiver is received and a first baseband complex signal is extracted. Likewise a second reflected electromagnetic signal reflected back in response to the second electromagnetic wave on the second transceiver is received and a second baseband complex signal is extracted. The first baseband complex signal is mathematically combined with the second baseband complex signal to cancel out a Doppler frequency drift therebetween to yield a periodic Doppler phase effect.

The dynamic amplifier further includes a power sensor configured to receive the power output signal and to generate a power indication signal corresponding to the power output signal, and a converter adapted to receive the power indication signal in order to generate a biasing signal corresponding to the power indication signal. The biasing signal is applied to the input amplifier so that the operating bias point of the power amplifier varies as a function of the power indication signal.

摘要： A non-contact detection technique of measuring both the frequency and the amplitude of periodic movement using a property of nonlinear phase modulation is provided. In one embodiment, the technique can utilize a 22-40 GHz radar sensor. Embodiments do not require calibration of signal amplitude for accurate measurement of movement amplitude. In addition, self-verification is possible. Furthermore, embodiments can provide measurements of frequency and amplitude using a very simple architecture. The method can be used to detect movements with amplitudes larger than 0.335 of the carrier wavelength for a fixed carrier frequency system and 0.214 of the minimum carrier wavelength for a frequency tunable system.
