激光测高仪 meaning in Chinese
laser altimeter
laseraltimeter
optical maser altimeter
Examples
- Satellite laser altimeter return waveform is sensitive to the vertical canopy structure and the change of underlying ground elevation . it is optimal for mapping forest structure . the return waveform and the processing method are described . the relationship between laser waveform and canopy structure parameters is explored ignoring the clumping effects . the clumping caused that structure parameters are different from the actual value . to solve this question , a model by 3 - d canopy structure parameters is needed
星载激光测高仪的回波信号能够灵敏反映地面植被组成和地表高度的变化,因此能够用于探测森林地貌;首先对星载激光测高仪的森林回波信号及其处理方法进行了介绍,探讨了在不考虑植被聚集情况下,植被组成与回波信号之间的关系;由于植被的聚集效应,例如树叶群集成树冠,会导致植被组成参数与真实值之间存在差异,这需要建立关于三维的空间分布模型加以解决。
