AI Article Synopsis
- The study introduces a new method to enhance the effective bandwidth of frequency-modulated continuous-wave (FMCW) ranging systems by combining the frequency sweeps from different laser sources.
- This approach leads to better range resolution, which improves as the frequency range increases.
- Experimentally, the technique shows a threefold improvement in range resolution compared to traditional FMCW methods by utilizing three different swept-frequency waveforms.
Article Abstract
We propose and demonstrate a novel approach to increase the effective bandwidth of a frequency-modulated continuous-wave (FMCW) ranging system. This is achieved by algorithmically stitching together the swept spectra of separate laser sources. The result is an improvement in the range resolution proportional to the increase in the swept-frequency range. An analysis of this system as well as the outline of the stitching algorithm are presented. Using three distinct swept-frequency optical waveforms, we experimentally demonstrate a threefold improvement in the range resolution of a three-sweep approach over the conventional FMCW method.
