Backscattering cross section

Backscattering cross section is a property of an object that determines what proportion of incident wave energy is scattered from the object, back in the direction of the incident wave. == Definition == === Physics === In physics generally, it is defined as the area which intercepts an amount of power in the incident beam which, if radiated isotropically, would yield a reflected signal strength at the transmitter of the same magnitude as the actual object produces.
