摘要
地物光谱反射特性通常采用直观的反射光谱曲线来研究, 基于此通过分析双向反射比系数随激光反射角度的变化规律来研究常见自然地物对1.06 μm激光的反射特性, 直观且便于外场数据采集。通过外场试验测得了10余种常见自然地物的双向反射比系数, 并按照激光反射能力对其进行了排序。研究表明, 杂草、风化岩石、龙眼树、灌木丛等自然目标对1.06 μm激光的反射能力较强。
Abstract
The reflectance spectral curve is often used to research spectral reflectance characteristic of features. According to this, 1.06 μm laser reflectance characteristic for common natural features is researched through analyzing the bidirectional reflection ratio changing with the reflectance angle of laser, which is explicit and easy to collect field data. The bidirectional reflection ratio of more than ten kinds of common natural features is measured through the field experiments, which is ordered according to the ability of laser reflectance. Research results show that natural targets such as weed, weathered rock, longan tree and shrub have stronger reflectance ability to 1.06 μm laser.
