摘要：

This paper demonstrates a sub-cm range resolution of a D-band (110-170 GHz) radar based on a bistatic BiCMOS mmWave IC with on-chip antennas. A wideband ring voltage-controlled oscillator (VCO) is utilized to generate a 20 GHz sweep bandwidth which translates to a frequency-modulated continuous-wave (FMCW) modulation bandwidth of 80 GHz by means of a built-in quadrupler in the radar transceiver chip. A demonstrator board is developed where the FMCW operation is investigated. A ranging precision of 75 mu m is verified at 0.5m without lenses, whereas a 6-dB effective range resolution of 6mm with Hann window was measured. A calibration against the nonlinearity in the radar output signal due to the very wide bandwidth is discussed. The calibrated range resolution approaches the theoretical limit of 3.8mm with Hann window.
