在这项研究中，我们使用一种称为高斯分解的技术，用于处理和校准用一种新型的小足迹机载激光扫描仪采集的数据，该扫描仪将从地球表面散射回来的激光脉冲的完整波形数字化。本文提出了一系列的高斯脉冲的波形建模的理论基础。以这种方式，为每个脉冲提供范围、幅度和宽度。使用外部参考目标也可以校准数据。校准方程考虑了距离、幅度和脉冲宽度，并提供了每个目标的后向散射截面的估计。该技术的适用性证明的基础上获得的维也纳市的RIEGL LMS-Q560数据。(C)2005年国际摄影测量和遥感学会（摄影测量和遥感学会）。Elsevier B. V.出版，保留所有权利。
In this study we use a technique referred to as Gaussian decomposition for processing and calibrating data acquired with a novel small-footprint airborne laser scanner that digitises the complete waveform of the laser pulses scattered back from the Earth's surface. This paper presents the theoretical basis for modelling the waveform as a series of Gaussian pulses. In this way the range, amplitude, and width are provided for each pulse. Using external reference targets it is also possible to calibrate the data. The calibration equation takes into account the range, the amplitude, and pulse width and provides estimates of the backscatter cross-section of each target. The applicability of this technique is demonstrated based on RIEGL LMS-Q560 data acquired over the city of Vienna. (C) 2005 International Society for Photogrammetry and Remote Sensing, Inc. (ISPRS).
