Simulation of Full-waveform Laser Altimeter Echo Waveform
Change of globe surface height is an important factor to study human living environment. The Geoscience Laser Altimeter System (GLAS) on ICESat is the first laser-ranging instrument for continuous global observations of the Earth. In order to have a comprehensive understanding of full-waveform laser altimeter, this study simulated the operating mode of ICESat and modeled different terrains’ (pl...
متن کاملCompressive simultaneous full-waveform simulation
The fact that the numerical complexity of wavefield simulation is proportional to the size of the discretized model and acquisition geometry, and not to the complexity of the simulated wavefield, is the main impediment within seismic imaging. By turning simulation into a compressive sensing problem—where simulated data is recovered from a relatively small number of independent simultaneous sour...
متن کاملIterative processing of laser scanning data by full waveform analysis
The latest developments in laser scanners allow capturing and digitizing of the full waveform of the backscattered pulse. The waveform can be analyzed for measurement features such as range, reflectance values and spreading of the pulse. These features are used to distinguish between locally planar surface elements and partly penetrable objects caused by partial occlusions. This presegmentation...
متن کاملRadiometric Calibration of Full-waveform Small-footprint Airborne Laser Scanners
Small-footprint airborne laser scanners (ALS) are lidar instruments originally developed for topographic mapping. In recent years ALS sensors are increasingly used also in other applications (forest mapping, building extraction, power line modelling, etc.) and their technical capabilities are steadily improving. While the first ALS systems only allowed determining the range from the sensor to t...
متن کاملInfluence of Varying Landforms and Flight Geometry on Echo Attributes of Full-waveform Airborne Laser Scanning Data
Full-waveform airborne laser scanning systems provide fundamental observations for each echo, such as echo width and amplitude. It is rarely to use amplitude for interpretation of point clouds due to its strong variability with different factors. A normalization process is usually applied. This study carried out a factorial experiment to investigate the effects of varying landforms and flight g...
