Millimeter-Wave OFDM-FMCW Radar-Communication Integration System Design

Remote Sensing
Frequency-modulated continuous wave (FMCW) and orthogonal frequency-division multiplexing (OFDM) technologies play significant roles in millimeter-wave radar and communication. Their combinations, however, are understudied in the literature.

Frequency-modulated continuous-wave laser ranging beyond the limits of bandwidth and phase noise

APL Photonics
Frequency-modulated continuous-wave (FMCW) laser ranging typically applies an interferometer and linear frequency-modulated (LFM) signals to measure the distance, in which precision and resolution are limited by the phase noise of laser and the bandwidth
