Related to Backscattering: backward scattering


1. The deflection of radiation or particles by electromagnetic or nuclear forces through angles greater than 90° to the initial direction of travel.
2. The radiation or particles so deflected.

back′scat′ter v.


1. (General Physics) the scattering of particles or radiation, such as sound waves, X-rays, or alpha-particles, by the atoms of the medium through which they pass, in the backward direction
2. (General Physics) the radiation or particles so scattered
3. (Military) a technique whereby very long-range radars locate targets hidden by the curvature of the earth. Radar beams are reflected off the underside of the troposphere onto the target and the return beams, similarly reflected, are measured
to scatter in this way


(ˈbækˌskæt ər)

1. the deflection of radiation by scattering in a direction opposite to the direction of incidence.
2. radiation scattered in this manner.


Refers to a portion of the laser energy that is scattered back in the direction of the seeker by an obscurant. See also laser.
