Reflectivity.
A flat metal plate placed at a right angle to a radar beam will always
reflect the maximum amount of energy. Curved surfaces will reflect much less, and
the effectiveness deteriorates as the curve becomes more acute.
A slanted surface will reflect much less due to reflection of most of the signal in a
direction other than the radar signal source.
A flat metal surface perpendicular to the radar signal gives a high amount of reflect-
ed return.
