backscattering

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.

Atmospheric backward scatter depletes 6%–9% of the incident solar beam before it reaches the earth's surface. In radar usage, backscatter refers only to that radiation scattered at 180° to the direction of the incident wave.
