Monitoring and assessing wetland diversity is crucial for its accurate preservation. Hyperspectral satellites have been proven effective detailed investigations of plant in many places. However, it's unclear whether spectral invert landscape diversity, the inversion accuracy varies with spatial scale. In this study, ZY1-02D hyperspectral remote sensing images Yellow River Estuary were supervised classified by support vector machine. Then, indices (i.e., community richness, Shannon-Wiener...
Wetlands are the one of ecosystems with highest biodiversity, ecological service functions and carbon storage. Affected by synergistic impacts human activities climate change, global wetland area has decreased 35 % since 1970, far-reaching implications on biodiversity loss. Compared manual ground investigations, remote sensing is considered to be most promising method for monitoring change in order formulate effective conservation strategies due its characteristics non-contact detection, low...
The surface water extraction algorithm based on satellite remote sensing images is advantageous as it able to obtain information in a relatively short time. However, when used extract large-scale, long-time series and complex terrain areas, there will be large number of misclassified pixels, amount image preprocessing work required. accuracy verification time-consuming laborious, the results may not accurate. climatic topographic conditions Bosten Lake Basin make more difficult monitor...
To improve the accuracy of GTEM cell applied in radiated EMI measurement, an noise extraction model and error compensation method based on variance analysis are proposed. High moments were employed to compare similarity two test curves between after calibration standard test. The experimental results for a PCB using voltage-driven show that can be improved significantly data nearly consistent with suggested approach.
Three kinds of electrical fast transient (EFT) pulse wave forms are defined with three sets formulas. Based on the formulas, spectral distribution EFT signals deduced by using method Fourier series expansion. An experiment is designed to verify deduction and measure electric field near equipment under test. The results show that strong at low frequency band (less than 200MHz, especially several hundred kHz). According radiation theory, magnetic may be stronger. So, associated equipments (AE)...
Monitoring and assessing wetland diversity is crucial for its accurate preservation. Hyperspectral satellites have been proven effective detailed investigations of plant in large areas. However, it's unclear if spectral can represent landscape or the inversion accuracy changes with spatial scale. In this study, we utilized support vector machine method supervised classification ZY1-02D hyperspectral remote sensing images Yellow River Estuary. Subsequently, indices (community richness,...
A radiated disturbance measurement is an important EMC test. However, it difficult to measure a highly-directive accurately. Current methods and software can't resolve this problem very well. Therefore novel accurate approach presented in paper: the scanning area of was divided into units process called "double-scan" introduced ensure receiving antenna could cover all units. Theoretical analysis simulation show that emission among whole can be detected effectively efficiently. disturbances measured
Three examples shows that with development of electronics technology and information technology, the diversity test samples brings new challenge to electromagnetic compatibility(EMC) engineers. For many "special" equipment under test(EUT), standard EMC measurement devices methods become not "compatible". Specially designed auxiliary equipments(AE) are in need make them compatible again. These specially AEs measuring system customized, will an important part instrumentation future.
