Synthetic Aperture Radar (SAR) is one of the most promising remote sensing technologies since it is not affected by clouds and lights. The SAR interferometric analysis, using phase information of backscattering echoes from objects on the earth’s surface, is successfully employed to quantify relative ground displacements due to natural disasters. In addition, the complex coherence derived from t...

In ecology, there have been attempts to establish links between the relative species abundance (RSA), the fraction of species in a community with a given abundance, and a power-law form of the species area relationship (SAR), the dependence of species richness on sampling area. However the SAR and other patterns in ecology often do not exhibit power-law behavior over an appreciable range of sca...

Stereo positioning is a important content for Spaceborne SAR imagery mapping, which is still lack of investigation depend on exterior orientation elements. In this paper, we firstly introduced the Range-Coplanarity (R-Cp) geometric imaging equation and its character for radar imagery, compared the difference and relationship between R-Cp and R-D model, and build stereo positioning rigorous mode...

This study introduces a new approach for modelling sea surface current variation using synthetic aperture radar (SAR). SAR Doppler frequency shift was computed by the ambiguous estimation and Wavelength Diversity Ambiguity Resolving algorithm (WDAR) and Multi Look beat Frequency (MLBF) RADARSAT-1 SAR standard mode data. In situ current measurements have been collected by using wave rider buoy (...

Purpose: To analyze the relationships between inhibitory activities on carbonic anhydrase IV and structures of substituted 1,3,4thiadiazole and 1,3,4-thiadiazoline disulfonamide through integration of compounds complex structure information by the use of Molecular Descriptors Family. Method: A number of forty compounds were used to generate and compute the molecular descriptors family and to bu...

It is well known that ocean waves are an important component of upper ocean dynamics. The synthetic aperture radar (SAR) has been widely used to measure ocean surface wave spectra from space since the Seasat satellite was launched in 1978. Many papers have been published dealing with the imaging mechanism and retrieval methodology. Schuler and Lee proposed a method to improve the measurement of...

The objectives of this study were to investigate the degree of spatial variability and variance structure of salinization parameters using classical and geostatistical method in Songnen Plain of China, which is one of largest saline-sodic areas in the World, and to analyze the relationship between salinization parameters, including soil salinity content (SC), electrical conductivity (EC), sodiu...

Existence of compound structure-activity relationship (SAR) and structure-selectivity relationship (SSR) are the fundamental hypotheses medicinal chemists rely on for lead selection and optimization during drug development. Although SAR has recently been statistically examined, previous studies did not cover SSR, an equally important assumption., For the current study, structural similarities (...
