The Waveform Digitization of Laser Return in Airborne Laser Remote Sensing Imaging
机载激光遥感成像的激光回波波形数字化技术

The fundamentals of airborne laser remote sensing imaging technology is introduced first in this paper. As a key part of the technology, the waveform digitizing circuit for acquiring laser return of ground targets is designed and its features are discussed. Then how to control digitizing and how to store digitized data are described. Finally some problems about pre_processing of digitized data are discussed and some typical results are given. The pre_processed results will be used as data sources to directly produce 3_D image and to sort ground objects.
