| Outline of Final Research Achievements |
In this study, optical-frequency-comb-based ranging technique is studied and developed using an FM-CW radar signals for high-precision ranging system. Optical modulation technique helps generating optical components with a high coherency each other by a single lightwave source. In the scheme, the FM-CW optical signals, which is provided by the comb components, has strong correlation in the waveforms. Therefore, multiple signal classification (MUSIC) technique can be applied to identify the beat notes in the FM-CW reception system. Finally, the high-precision ranging results are provided by the optical frequency comb system. Also, we developed high-precision millimeter-wave signal generation by the optical frequency comb source and broadening technique of the optical frequency comb bandwidths by synchronization of multiple frequency comb signals. We hope these fundamental technique will help realizing high-precision ranging solutions based on the frequency combs.
