I purchased a Doppler radar that can run in both CW and FMCW modes. I don't understand how to operate the radar in FMCW mode. I would like to understand what I need to do to get my radar to run in FMCW. I have the spec sheet and it has a VCO with default output of $25\textrm{GHz}$.

Any help would be great. Currently I leave the VCO open as per documentation so that the output Tx is $24\textrm{GHz}$ but is the default operation FMCW?
