radar cross section of a monopole antenna

Hi.
I have simulated radar cross section (RCS) of a monopole antenna in a frequency range(for example VHF band).
But I don't have any reference to compare my results.
is there anyone who has a paper of figure from RCS of monopole antenna?
in RCS calculation of monopole,do I have to consider ground plane effect?
thanks

Please provide some more info: length of monopole antenna (in lambda), antenna termination (that is load as seen by the antenna), size of ground plane, etc? This will help you to get useful answers.

So,in RCS calculation of a monopole antenna,do I have to consider ground plane?
my monopole antenna is quarter wavelength that is excited by a coaxial cable.and my frequency range is VHF.
