The spectrogram shows that the signal is strong (large volume of scatters) with focused frequency range (uniform speed).
Also, we can see that the bulk motion generated a sharp peak, which represents large volume of scatter moving all together.
Here the electric field amplitude is normalized relative to the maximum amplitude in the focal volume in the absence of scattering.
Galactic halo, in astronomy, nearly spherical volume of thinly scattered stars, globular clusters of stars, and tenuous gas observed surrounding spiral galaxies, including the Milky Way the galaxy in which the Earth is located.
These found that the simplest IDI analysis produced results similar to the apparent velocity of the FCA, and that the presence of (apparent) discrete scattering centers was inevitable even in the case of volume scattering.
Through analyzing the changes in the scattering mechanism before and after POA compensation for the three kinds of buildings, we found that the increase in the amount of double-bounce scattering component and the reduction in the amplitude of the volume scattering component of the oriented buildings are greater than for the collapsed buildings.
Before and after POA compensation, the relative contributions of each scattering component for the parallel buildings basically remain the same, while the relative contribution of double-bounce scattering for the oriented buildings is more than doubles, and the relative contribution of volume scattering significantly decreases.
The results of the measurements of the volume scattering function β and degree of linear polarization P of the carbonaceous graphite dust particles that were sprayed in front of the laser beam by using an aerosol sprayer were subsequently compared with theoretically generated Mie plots with estimated parameters.
Moreover, S appears in this case to be a smooth correction factor (≠ 1 in general) with meaningful values which can be used to determine the effective radius and the core volume of the scattering particles (large wavelengths) and give insights into the surface roughness (small wavelengths).
From the last section it can be seen that, in the powder diffraction experiment, when the distribution of orientations is very large, the captured volume of the scattering in Ω and X will include the whole distribution.
