For Doppler centroid estimation, I'm trying to implement cross correlation coefficient and phase of cross correlation coefficient, but facing problem in that.
please guide for these two equations.
t_az = [-0.05, 0.05]; % azimuth time (zeta)
A = [1,0.5*1j];
PRF = 1500;
F_dc = 100;
t = -0.2: 1/PRF: 0.2; % range time (tau)
B = 300; %HZ
% X = sinc(B*t);
s = zeros(1, length(t));
for i = 1:length(t_az)
s = s+ A(i)*sinc(B*(t-t_az(i))).*exp(1j*2*pi*F_dc*(t-t_az(i)));
end
%%
sigma = 0.01;
N = sigma/sqrt(2)*(randn(1,length(s))+1j*randn(1,length(s))); % Noise
s = s+N; %signal plus noise
