Full-waveform topographic lidar: State-of-the-art
ISPRS Journal of Photogrammetry and Remote Sensing, 2009Nous présentons une étude bibliographique sur les systèmes lidar topographiques à retour d'onde complète, aussi nommés lidar full-waveform, ainsi que sur les données générées. Le contexte de cette étude se situe dans le domaine de la télédétection aérienne et spatiale par systèmes actifs.

Simulating full-waveform lidar
SPIE Proceedings, 2010A simple Monte Carlo model of laser propagation through a tree is presented which allows the simulation of fullwaveform LIDAR signatures. The model incorporates a LIDAR system and a 'natural' scene, including an atmosphere, tree and ground surface. The PROSPECT leaf reflectance model is incorporated to determine leaf radiometric properties.

Compressive full waveform lidar
SPIE Proceedings, 2017To avoid high bandwidth detector, fast speed A/D converter, and large size memory disk, a compressive full waveform LIDAR system, which uses a temporally modulated laser instead of a pulsed laser, is studied in this paper. Full waveform data from NEON (National Ecological Observatory Network) are used.

Sparse representation of full waveform lidar data
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012Full Waveform Data (FWD) has been increasingly becoming available on modern airborne LiDAR systems. Since the waveform signal is noisy and rather sparse by nature, the compressed FWD representation has several advantages. First, the reduced data volume makes the storage and transmission of waveform data faster and more economic.

AdaptLidarTools: A Full-Waveform Lidar Processing Suite
2019 15th International Conference on eScience (eScience), 2019AdaptLidarTools is a software package that processes full-waveform lidar data. Full-waveform lidar is an active remote sensing technique in which a laser beam is emitted towards a target and the backscattered energy is recorded as a near continuous waveform.

A Photon-Counting Full-Waveform Lidar*
Chinese Physics Letters, 2019Abstract We present the results of using a photon-counting full-waveform lidar to obtain detailed target information with high accuracy. The parameters of the waveforms (i.e., vertical structure, peak position, peak amplitude, peak width and backscatter cross section) are derived with a high resolution limit of 31 mm ...

Generalized Gaussian decomposition for full waveform LiDAR processing
Measurement Science and Technology, 2022Abstract Waveform decomposition techniques are commonly used to extract attributes of targets from light detection and ranging (LiDAR) waveforms. Since the shape of a real LiDAR waveform varies for different systems, the conventional models (e.g.

Noise reduction algorithm for full-waveform lidar signal
2011 IEEE International Conference on Signal and Image Processing Applications (ICSIPA), 2011Noise is an inevitable problem which affects coherent imaging systems and consequently reduces the capability of lidar systems to resolve variations in the target heights. Common noise-reduction procedures, including moving Mean and Median filters, operate on a global level and do not perform adaptively on different segments of the backscattered signal.

Empirical Comparison of Full-Waveform Lidar Algorithms
Photogrammetric Engineering & Remote Sensing, 2011As third-party lidar software manufacturers are increasingly adding support for full-waveform data, a common question is which algorithm(s) to implement. To this end, a new approach is needed to compare and contrast various lidar waveform processing strategies from a practical, operational perspective. Quality and type of information output, processing

Temporal super-resolution in full waveform lidar
Emerging Imaging and Sensing Technologies for Security and Defence III; and Unmanned Sensors, Systems, and Countermeasures, 2018To obtain high ranging resolution and to record full waveform signals, full waveform LiDAR requires short pulse width laser sources, high bandwidth sensors, high bandwidth A/Ds, and large on-board memories. To relax these requirements, temporal super-resolution is studied in this paper.
