Tracking Beyond the Unambiguous Range with Modulo Single-Photon Lidar

Samuel Fernández-Menduiña, Joshua Rapp, Hassan Mansour, M. Greiff, Kieran Parsons

ICASSP 2024accepted

In single photon lidar (SPL), the laser repetition rate sets the maximum distance that can be recovered unambiguously. Conventional SPL extends this maximum recordable depth by reducing the repetition rate; however, the slower acquisition speed limits the number of received photons, which may be ins…

Phase Unwrapping in Correlated Noise for FMCW Lidar Depth Estimation

A. Ulvog, Joshua Rapp, Toshiaki Koike-Akino, Hassan Mansour, Petros Boufounos, Kieran Parsons

ICASSP 2023accepted

In frequency-modulated continuous-wave (FMCW) lidar, the distance to an illuminated target is proportional to the beat frequency of the interference signal. Laser phase noise often limits the range accuracy of FMCW lidar, and existing frequency estimation methods make overly simplistic assumptions a…
