Sentinel-1卫星TOPS模式影像通常在几何配准的基础上,再次利用Burst重叠区域进行增强谱分集处理以实现高精度配准。几何配准主要依赖卫星轨道参数,难以进一步提高其配准精度,因此Sentinel-1影像配准的关键则是通过增强谱分集准确估计出几何配准后的残余偏移量。然而,增强谱分集易受失相干噪声等因素的影响,低相干条件下难以满足0.001像素的配准精度要求。因此本文首先针对单基线条件下的增强...
3D reconstruction of the urban environment constitutes a well-studied problem in the field of photogrammetry and computer vision, attracting the growing interest of the scientific community, for many ...
Severe weathers such as heavy rainfall, floods, strong wind, and lightning are closely related with the strong convection activities of atmosphere. Overshooting tops sometimes occur by deep convection...
针对基于地球同步轨道条带模式合成孔径雷达(synthetic aperture radar,SAR)发射无人机循序渐进对地扫描模式SAR接收组成的星机双基结构(GEO-bistatic radar with GEOSAR and UAVSAR, GEO-UAV BiSAR),提出了该工作模式下的成像算法。首先,基于泰勒展开原理推导了双基斜距,考虑到该双基斜距的空变特性,应用级数反演方法推导了具有距...
针对斜视循序扫描地形观测(terrain observation by progressive scans, TOPS)合成孔径雷达(synthetic aperture radar, SAR)模式,提出了一种新的全孔径成像处理方法。首先对距离走动校正后的数据进行方位预处理得到无模糊的二维频谱,在此基础上采用修正的线频调变标算法完成距离脉压及距离徙动校正;然后在距离多普勒域进行频域非线性变标(fr...
Boosted Semileptonic Tops in Stop Decays 。
In this work, we study the behavior of the singular solutions of the problem governed by the adjunct of the laplacian operator affected by a weight function in a polygon. First, the study will be done...
We perform a joint analysis of the prediction of composite Higgs models for the dis-crepancies of the forward-backward asymmetries of top and bottom quarks at Tevatron and LEP+SLC, respectively.
In this study, the effects of molasses (M) and ground wheat (GW) additions on the quality of groundnut (Arachis hypogaea L.) (GN), sweet potato (Ipomoea batatas L.) (SP) and Jerusalem artichoke (Helia...
Four male crossbred beef steers about 2 years old were used in a 4횞4 Latin square design to investigate the effect of pelleted sugarcane tops on voluntary feed intake, rumen fermentation and di...
Four rumen-cannulated cows (330 kg average weight at 4 years) were used to evaluate the supplement of ensiled cassava tops (ECT) (variety KM 94, 39% DM) on rumen functions, thyroid hormones and liver ...
This paper on Rocky Mountain poetry and the resonance of the Great Divide begins and closes in memoir.1 In between it reflects on mountain realities and the literary metaphors to which the realities g...
Fifteen crossbred cattle bulls of about 22-24 months age (mean body weight ranged from 291.0 to 298.1 kg) were randomly divided into 3 groups of 5 animals following randomized block design. Animals in...
The study aimed to evaluate the influence of molasses in ensiling cassava and Gliricidia tops, common crop residues in the farming systems of Vietnam. Four levels of sugarcane molasses: 0, 30, 60 and ...
