How to generate 24Ghz FMCW waveform?

I am trying to generate a FMCW waveform using phased array toolbox but i cannot understand as there is no carrier frequency option in the object. I need to generate a 24Ghz signal with 256 samples in each of 128 chirps.
fmwaveform = phased.FMCWWaveform('SweepBandwidth',bandwidth,...
'SampleRate',1e6,'OutputFormat','Samples','SweepTime',256e-6,'SweepDirection','Up',...
'NumSamples',256);
xref = fmwaveform();
figure
plot(fmwaveform)

Hey Abdul,
I understand that you want to configure carrier frequency option using phased array toolbox to generate a 24GHz signal with 256 samples in each of 128 chirps.
Most simulations would simulate the effect on the baseband signal instead of a signal at 24GHz. In that case, the value of 24 GHz will be used to determine the path loss, the antenna pattern, and so on but the signal is not sampled at 24 GHz. This is mainly due to:
Please go through the “Signal Simulation” section of the below linked MATLAB documentation to get information regarding “Target Model” with specific carrier frequency, and “Modelling waveform radiation and collection”, which enabling carrier frequency incorporation: https://ww2.mathworks.cn/help/pdf_doc/phased/phased_gs.pdf
I hope this helps!
