measure of the capability of the object to scatter the transmitted radar power

Note 1 to entry: Radar cross section is calculated as sigma = lim_(R ->oo) 4 pi R^2 (abs(E_s)^2) / (abs(E_i)^2) where sigma is the radar cross section; E_i is the electric-field strength of the incident wave; E_s is the electric-field strength of the scattered wave at the radar with a distance R away from the target.

Note 2 to entry:  2 to entry: Radar cross section has the dimensions of area, with the unit of square metres. Usually, it is expressed in the form of a logarithm with the unit of dBsm as follows sigma_(dBsm) = 10 log_(10) sigma
