摘要

A practical sub-dechirp receiving technology for the double-sideband linear frequency modulation continuous wave (DSB-FMCW) lidar has been developed and experimentally demonstrated. Different from the traditional dechirp method, the local oscillator (LO) in the proposed technology has an independent modulator. This design can flexibly control the frequency of interference signal by adjusting the m...
