Trent reverse reflection device is adopted to offset the effect caused by beat and cross sliding during displacement or vibration and to enhance measurement sensitivity and accuracy nearly one time.
The range measurement of the FMCW radar is based on the estimation of the frequency of the beat-note signal.
