function [rcs]=rcs_aspect(scat_spacingfreq)
%%%This function demonstrates the effect of aspect angle on RCS
%%%%Plot scatterers separated by scat_spacing meter.Initially the two
%%%%scatterers are aligned with radar line of sight The aspect angle is
%%%%changed from 0 degrees to 180 degress and the equivalent RCS is
%%%%computedPlot of RCS versus aspect is generated
eps=0.000001;
wavelength=3e8/freq;
%Compute aspect angle vector
aspect_degrees=0:0.05:180;
aspect_radians=(pi/180).*aspect_degrees;
%Compute electrical scatterer spacing vector in wavelength units
elec_spacing=(13*scat_spacing/wavelength).*(cos(aspect_radians));
%cpmpute RCS(RCS=RCS_scat1+Rcs_scat2);
%scat1 is taken as phase reference point
rcs=abs(1+cos((13*pi).*elec_spacing)+i*sin((13*pi).*elec_spacing));
rcs=rcs+eps;
rcs=20*log10(rcs);%RCS in dBsm
%Plot RCS versus aspect angle
