Zou et al. (2008) [21] presented weighted-average of all possible choice values approach soft sets under incomplete information system in decision making. However, the is hard to understand and involves a great amount computation. In order simplify approach, we present simplified probability directly instead information, demonstrate equivalence between approach. Finally, comparison results show that proposed relatively less computation easier implement as compared with
The primary objective of this research is to study the relationship between surface movement and hydrological triggers a large active landslide in Three Gorges Reservoir (the Shuping landslide). When was reactivated June 2003 owing impoundment Dam, measurement began through use manual global positioning system (GPS) monitoring. Since 2012, near-real-time data with fine temporal resolution have been collected continuous automatic GPS. In total, more than 10 years recorded for landslide....
A wind direction retrieval algorithm using spaceborne global navigation satellite system reflectometry (GNSS-R) in nonspecular geometry is presented. This article first focuses on investigating the influence of scattering strength purely specular and geometry. The sensitivity scattered GNSS signals to demonstrated despite weaker power level. Therefore, a based geophysical model function (GMF) whose parameters are parameterized as look-up-table proposed. Then, spatial resolution link GNSS-R...
This paper presents a monitoring system based on Global Navigation Satellite System (GNSS) reflected signals to provide real-time observations of sea conditions. Instead computer, the uses custom-built hardware platform that incorporates Radio Frequency (RF), Field Programmable Gate Array (FPGA), Digital Signal Processing (DSP), and Raspberry Pi for signal processing. The suggested structure completes navigation signal's positioning as well feature extraction. tests are conducted confirm...
Spaceborne global navigation satellite system reflectometry has been used to retrieve wind speed, but few studies have directly detected tropical cyclones from spaceborne GNSS-R observations. Moreover, it is challenging solve the multivalued dependence of observable on speed unambiguously and accurately in cyclone conditions. This paper presents a single-pass detector coarse estimation approach position using full delay-Doppler map (FDDM). When specular point passes through cyclone, FDDM...
The elevation angle influence on coastal GNSS-R ocean code-based altimetry for GPS signals (L1 C/A and L5) BDS B1 is investigated, the corresponding correction method presented. study first focuses method, including general experiment geometry code delay estimation using single-point tracking algorithm. peak power maximum derivative are used as location of specular point. Then, sensitivity height retrieved above to analyzed based Z-V model. It can be seen that has a significant retrieval,...
The signals at higher elevation angles could be received by a left-handed circularly polarized (LHCP) antenna because LHCP components dominate the reflected angles. This letter explores four-channel interference method of dual-antenna global navigation satellite system (GNSS) reflectometry capable and its application in retrieving water level. Compared to single-antenna observation using oscillating signal-to-noise ratio (SNR), due capability receiving high angles, proposed has temporal...
