摘要
首先介绍了机载激光遥感成像技术的基本原理 ,讨论了其关键组成部分的地面目标激光回波波形数字化电路的设计及其组成特点 ,叙述了该波形数字化电路的时序设计和数据存储结构 ,最后讨论了波形数字化结果的数据预处理方法及相关问题 ,得到了系统试验运行中获取的激光回波的有关预处理结果 ,它们将作为进一步生成地面三维图像和目标分类的数据源。
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.
