backscattering


backscattering

[′bak¦skad·ə·riŋ] Also known as back radiation; backward scattering. (communications) Propagation of extraneous signals by F- or E-region reflection in addition to the desired ionospheric scatter mode; the undesired signal enters the antenna through the back lobes. (electromagnetism) Radar echoes from a target. Undesired radiation of energy to the rear by a directional antenna. (physics) The deflection of radiation or nuclear particles by scattering processes through angles greater than 90° with respect to the original direction of travel.
