hi
i am working on moving target detection using the frequenct modulated continuous wave NOISE RADAR. i have come across many examples in matlab which are quite helpful. my work ios something similar to this example ("https://www.mathworks.com/help/phased/examples/automotive-adaptive-cruise-control-using-fmcw-technology.html")
my question is when i generate and modulate noise signal with the fmmod() with the same fc and fs in above mentioned examples it shows error fs>2*fc. should i use a different sampling frequency for this and how do i add my generated noise signal as an input the above example? is the below code correct?
L=1100;
MU=0;
sigma=2;
wgn=sigma*(randn(L,1))+MU;
figure();
plot(wgn);
xlabel('sample');
ylabel('sample values');
grid on;
fs=200e6;
fd=100;
radarsig=fmmod(wgn,fc,fs,fd);

Hi. can you share your developed codes of mti and others related to fmcw radars? im working on a similar task and it would be of great help. Thank you.
