    Abstract: A motion detection device is provided. The motion detection device includes a first antenna, a voltage-controlled oscillator, a phase detector and a signal processing unit. The first antenna receives a first signal generated by a second signal reflected by a target object, so as to output the first signal to the phase detector or the voltage-controlled oscillator. The voltage-controlled oscillator receives first signal or the second signal and receives a frequency adjustment signal, so as to generate an oscillating signal according to the frequency adjustment signal and the one of the first signal and the second signal. The phase detector receives the oscillating signal and another one of the first signal and the second signal, and generates a first phase output signal and a second phase output signal. The signal processing unit estimates motion parameters of the target object according to the first and the second phase output signal.

    Abstract: A motion/vibration sensor includes a transmit/receive antenna unit, an oscillation unit and a frequency-mixing unit. The transmit/receive antenna unit receives an output signal from the oscillation unit and transmits a detection signal toward at least one object. The detection signal is reflected by the object as a reflected detection signal and received by the transmit/receive antenna unit. The oscillation unit receives the reflected detection signal from the transmit/receive antenna unit for self-injection locking; and the frequency-mixing unit receives the reflected detection signal from the transmit/receive antenna unit for frequency demodulation. The frequency-mixing unit mixes and demodulates the reflected detection signal from the transmit/receive antenna unit with the output signal from the oscillation unit into a baseband output signal which represents a motion/vibration information.

    Abstract: A motion/vibration detection system and method therefore are provided. The system includes a transmitter and a receiver. The transmitter includes a transmit/receive antenna unit and a first oscillator. The receiver includes a receiving unit and a demodulation unit. The transmit/receive antenna unit receives an output signal from the first oscillator and transmits a detection signal. The detection signal is reflected from at least one object under detection into a reflected detection signal, which is received by the transmit/receive antenna unit. The transmit/receive antenna unit injects the reflected detection signal into the first oscillator and accordingly the first oscillator is under a self-injection locking mode. The receiving unit receives the detection signal. The demodulation unit demodulates the detection signal received by the receiving unit into a baseband output signal, to extract at least one motion/vibration information of the objection under detection.
