Backward Scatter
The scattering
of radiant energy into the hemisphere of space bounded by a plane normal to
the direction of the incident radiation and
lying on the same side as the incident ray; the opposite of forward
scatter. Also called back scattering .
Atmospheric backward scatter depletes 6 to 9 percent of the incident
solar beam before it reaches the earth's surface.
In radar usage,
backward scatter refers only to that radiation scattered at 180 to the
direction of the incident wave.
