Soil moisture is a governing parameter in many complex environmental processes from the disciplines of meteorology, hydrology and agriculture. Since rainfall is partitioned into runoff and infiltratio...
Radar interferometry is a technique which makes use of interfered signal of two radar echoes for topographic elevation and terrain element mapping. ERS Synthetic Aperture Radar (SAR) tandem pair with ...
This study aims to assess the contribution of ENVISAT ASAR data for the monitoring of the littoral plains of Kourou and Saint Laurent du Maroni (French Guyana).
Space-borne wind scatterometers are important element of microwave remote sensing systems because of their proven ability to make all-weather measurements of wind vector over the ocean. In addition t...
In this paper, the potential of multitemporal ERS-1/2 InSAR data for detecting urban land-cover changes is investigated on a test area within Shanghai city, China. A new unsupervised change-detection...
TREE SPECIES CLASSIFICATION USING ERS SAR AND MODIS NDVI IMAGES     Forestry  Land Cover  Classification  Fusion  Optical  SAR  Multitemporal       font style='font-size:12px;'> 2015/7/30
A set of ERS SAR and optical MODIS-images were classified to land cover and tree species classes. Different methods for pixel and decision based data fusion were tested. Classifications of featurese...
Mani Earthquake, occurred on Nov. 8, 1997 in Tibet, China, is the strongest event in China since 90’s in 20 century. Investigation and research of its principle and geometry, dynamics related to sur...
Burn scar identification and fire damage assessment was done using ERS-2 SAR radar images in East Kalimantan, an Indonesian province severely affected by wildfires during a drought period in 1997/19...
THE INTERPRETATION OF ERS-1 AND ERS-2INSAR DATA FOR THE MINING SUBSIDENCE MONITORING IN UPPER IN SILESIAN COAL BASIN, POLAND.
INTEGRATION OF MULTITEMPORAL ERS.2 SAR AND LANDSAT TM DATA FOR SOIL MOISTURE ASSESSMENT.
Information on human development and database building are crucial for providing the basic needs and infrastructure in fast growing urban areas, as in developing countries. To obtain this information ...
In the literature of psychophysics and neurophysiology, many studies have shown that both global and local features are crucial for face representation and recognition. This paper proposes a novel fac...
在与运动相关的脑-机接口(Brain-Computer Interface, BCI)研究中,如果样本规模小,共同空间模式(Common Spatial Patterns, CSP)滤波算法对离群点(可能为噪声)敏感,鲁棒性不好。为此该文提出自适应空间滤波(Adaptive Spatial Filter, ASF)算法,抽取滤波后脑电信号的方差作为特征,并寻找最优滤波器使两类特征中心的比值最大。与...
ERS-1遥感卫星高速数据接收系统     遥感卫星  高速数据接收系统       font style='font-size:12px;'> 2008/10/31
该设备首次把通用环解调技术应用于遥感卫星高速数据接收系统,使系统的误码性能和快捕带指标明显优于引进的同类设备。运用该系统接收的原始数据带作为成功范例,已拷贝给ESA进行存档。该项成果为中国遥感卫星地面站升级工程起到重要作用,对提高我国资源管理能力的国际声望有重要的社会效益。
该文建立了反向传播人工神经网络 (Back Propagation Artificial Neural Network, BP-ANN)和遗传算法 (Genetic Algorithm, GA)的BP-ANN/GA混合算法。利用GA算法的全局优化能力优化BP-ANN的初始权值,克服了传统BP-ANN收敛速度慢,容易陷入局部最小的缺点。BP-ANN/GA混合算法对Landsat ETM+4, 5, ...
