rectangular-coordinate graph of the measured radiation, shown in
figure 4-11, view A, is a straight line plotted against positions around the
circle. View B shows the polar-coordinate graph for the same isotropic source.
Figure 4-11. Comparison of Rectangular and Polar-Coordinate Graph for an Isotropic Source
4-55. In the rectangular-coordinate graph, points are located by projection
from a pair of stationary, perpendicular axes. In the polar-coordinate graph,
points are located by projection along a rotating axis (radius) to an
intersection with one of several concentric, equally spaced circles. The
horizontal axis on the rectangular-coordinate graph corresponds to the circles
