Abstract
Bandwidth efficient coherent lidar based on phase-diversity detection is reported for the first time, to the best of our knowledge, which allows the doubling of bandwidth efficiency through the simultaneous utilization of the in-phase () and quadrature () components. By maintaining RF phase continuity between linearly frequency-chirped and components through digital signal processing, the range resolution of the lidar system can be improved.
