Exploration of Levy Statistics in Random modulation parallel LiDAR based on chaotic modulation instability in microcombs
Abstract
Currently employed LiDAR in autonomous driving are based on time-of-flight (TOF), frequency modulation continuous wave (FMCW) and random modulation continuous wave (RMCW) approaches. RMCW is of particular interest for its advantages of FMCW, such as direct velocity measurement enabled by coherent detection and low peak power operation due to the continuous wave regime. However, in contrast to FMCW, it has no ambiguity in detected range, no phase wrap uncertainty, simplified signal processing for static targets based on cross-correlation operator, and it does not rely on a laser source with demanding requirements of well-controlled, linear, and broad chirps. The research will investigate a novel method of providing random modulation to laser sources without added hardware and study the behavior of the LIDAR operating in RMCW mode.
