Abstract

Optical frequency-modulated continuous-wave (FM-CW) signal generation based on a high-precision optical modulation technique is successfully demonstrated for full-band millimeter-wave (MMW) radar in the W-band (75-110 GHz) and detection of an optical fiber cut by optical frequency domain reflectometry. The optical frequency up-converter based on radio-over-fiber technology creates a high-speed pulse of the FM-CW signal with broad bandwidths, and the signal degradation agrees with theoretically estimated values. The dual purpose of the optical FM-CW signal for MMW and optical imaging will be useful for a distributed antenna radar system with a MMW signal and sensing of the optical distribution network.
