After correcting  which greatly improves the imaging quality of TDI CCD space camera. 2011 IEEE.  a model of image motion calculation of nadir has been introduced  the calculation and analysis of the model shows that: the maximum error of image motion velocity about 1.72% has been decreased to 0.06%  and the influence of the geocentric distance error to the relative error of image motion velocity has been analyzed with the model   Factors controlling the spatial variability of surface soil moisture within revegetated-stabilized desert ecosystems of the Tengger Desert, Northern China 期刊论文  iSwitch采集 HYDROLOGICAL PROCESSES, 2009, 卷号: 23, 期号: 11, 页码: 1591-1601 作者:  Pan, Yan-Xia;  Wang, Xin-Ping 收藏  |  浏览/下载：34/0  |  提交时间：2019/10/08 surface soil moisture  coefficient of variation  relative elevation  shrub coverage  herbage coverage  soil particle size
