專利摘要 |
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. |
