    Abstract: A phase-tracking self-injection-locked (SIL) radar includes an SIL oscillator, a phase-tracking SIL loop and a frequency-locked loop. The SIL oscillator generates an electrical oscillation signal and receives an electrical injection signal related to the electrical oscillation signal for self-injection locking. The phase-tracking SIL loop receives the electrical oscillation signal and outputs the electrical injection signal to the SIL oscillator with a constant phase difference between the electrical oscillation signal and the electrical injection signal. The frequency-locked loop receives the electrical oscillation signal and produces an electrical control signal to control the phase-tracking SIL loop or the SIL oscillator for eliminating the frequency shift of the SIL oscillator caused by the phase-tracking SIL loop. Accordingly, the phase difference between the electrical oscillation signal and the electrical injection signal is maintained at 0° or 180° such that the phase-tracking SIL radar operates at optimal detection points.

    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.
