摘要：
We demonstrate amplitude-modulated continuous-wave (AMCW) ranging system using resonant-tunneling-diode (RTD) THz oscillator. The reflected signal of amplitude modulated output of the RTD from an object was received and demodulated. The distance to the object was determined by measuring the phase difference between the demodulated signal and the reference of the modulation signal. The carrier frequency is 522 GHz, and the modulation frequency is 1.2 GHz. The error of the measured distances was less than 10 mm The resolution can be improved by increasing the modulation frequency.
