Morphological tools for range-interval segmentation of elastic lidar signals
(2007)
Text en actes de congrés
Accés obertThis article presents a preliminary semi-automated range-interval segmentation toolset for the identification of: 1) the apparent range of full overlap, 2) the clear-sky level (i.e., the molecular level), and cloud layers ... -
Motion compensation study for a floating Doppler wind lidar
(Institute of Electrical and Electronics Engineers (IEEE), 2015)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper addresses a cardanic frame as mechanical-compensation device for a Doppler-wind lidar installed on a floating sea buoy as the “moving” lidar. From the methodological point of view, the horizontal wind speed (HWS) ... -
Motional behavior estimation using simple spectral estimation: application to the off-shore wind lidar
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Text en actes de congrés
Accés obertThis paper proposes two methods to estimate the so-called “characteristic motional period” of a floating wind-lidar buoy. These techniques aim to characterise the buoy's pitch and roll tilting as simple harmonic motions ... -
Motivating a synergistic mixing-layer height retrieval method using backscatter lidar returns and microwave-radiometer temperature observations
