I m simulating a target at 45 degrees azimuth and with a certain doppler..I m using the following code to find angle doppler response...However, i get an error of 15 degrees in angle...
%% Beamforming and doppler processing
sigvol = 0 (fs *革命制度党,128128);
sigvol1 = sigvol;
tcsig1 = zeros(fs*pri,N,M);
因为我=施用
temp1 = shiftdim(tsig(i,:,:));
temp2 = fftshift(fft(temp1,128,1),1); %% doppler processing
temp3 = fftshift(fft(temp2,128,2),2); %%beamforming
sigvol(i,:,:) =temp3 ;
end
ad = pow2db(abs(squeeze(sigvol(128,:,:))));
figure(2)
angle_axis = linspace(-90,90,128);
doppler_axis = -prf/2:prf/128:(prf/2)-(prf/128);
imagesc(angle_axis,doppler_axis,ad.');
colormap(jet)
colorbar
xlabel('Angle')
ylabel('Doppler')
