The beam pattern shown in Part A of Figure 140 would provide a radar
set with accurate
a.
azimuth information.
b.
elevation information.
c.
azimuth and elevation information.
d.
azimuth, elevation, and range information.
17.
The type of reflector that would produce the beam pattern shown in
Part B of Figure 140 can be described best as a
a.
paraboloid.
b.
metallic lens.
c.
vertically mounted orange peel.
d.
horizontally mounted orange peel.
