function rcscd=rcsChaff(frequency)
% RCSCHAFF Maximum radar cross section of a single chaff dipole
% 
%   rcscd=rcsChaff(wavelength)
% 
%   rcscd = Maximum RCS of a chaff dipole [m^2]
%   frequency = Operating frequency of targeting radar [Hz]

%   AIM:
%   To find the maximum radar cross section (RCS) of a single chaff dipole.
% 
%   TECHNICAL BACKGROUND:
%   Chaff is made up of small aluminium strips. There is a coating on these
%   strips which makes the chaff strip conductive. An ideally orientated
%   chaff dipole, which is usually half the length of the targeting radar's
%   wavelength, has a RCS approximately equal to 0.86 x wavelength^2.
