Grids and lines for fixed mode and moving mode for three-dimensional data measurements.
Note that the polarization orientation of the antennas is the same for each measurement point on the grid, or
along the profile lines.

fIGURe 7.13
The process of constructing a three-dimensional display from a series of two-dimensional
lines: (a) series of two-dimensional lines and (b) three-dimensional full-color (or gray scale) block view,
(c) horizontal slices and vertical cross sections, and (d) adjustment of color scale (gray scale) and opacity to
emphasize the important features in a three-dimensional block.
