co-polarized共极化;cross-polarized交叉极化
A local positioning system using co-polarized and cross-polarized radar mapping is provided. In one embodiment of the method, at least a first electromagnetic pulse having a first polarization is transmitted. A first return signal preferentially having the first polarization is received over a ...
Copolarized and cross-polarized bistatic scattering cross sections are measured for both transverse electric and transverse magnetic incidence at 20°. For isotropic surfaces, backscattering enhancement exists for both copolarized and cross-polarized returns and is found to be a function of the surface ...
Co- and cross- polarized light has shown enhanced accuracy. Accuracy of co-minus cross-polarized light is poor. It is fast, noninvasive and quantitative and, with further developments, has the potential to become a regular screening tool in future. 展开 ...
and 𝜙𝑋𝑃𝐷=∠𝑆𝐻𝑉𝑆∗𝑉𝑉=𝜙𝐻𝑉−𝜙𝑉𝑉ϕXPD=∠SHVSVV*=ϕHV−ϕVV (5) are, respectively, the CPD and cross-polarized phase difference, where ∠ and ∗* stand for the phase part and complex conjugate operator, respectively. For most natural ...
This study aimed at analyzing the effect of Synthetic Aperture Radar (SAR) imaging parameters and environmental conditions on the standard deviation of the co-polarized phase difference ( σ φ C ) evaluated over sea surface. The latter was shown
The wrap of the Maui Jim Kanaio Coast polarized sunglasses deliver enough versatility to be worn for both outdoor activities and casual wear.
The sea surface normalized radar backscatter cross-section (NRCS) and Doppler velocity (DV) exhibit energy at low frequencies (LF) below the surface wave peak. These NRCS and DV variations are coherent and thus may produce a bias in the ... YY Yurovsky,VN Kudryavtsev,SA Grodsky,... - ...
Banyans polarized sunglasses shade your eyes from the sun's harmful rays using Maui JimPolarizedPlus®2 technology. They also boost colors and eliminate glare,
Erratum to: High-Frequency and -Field Electron Paramagnetic Resonance of High-Spin Manganese(III) in Axially Symmetric Coordination Complexes We report X-ray emission spectra of Fe(III), Fe(II), and Co(II) spin-crossover compounds in their high-spin and low-spin forms. It is shown that al...
