FMCW radar with trapezoidal chirp

1) i want to create FMCW radar with trapezoidal chirp with the following parameters:

Fc=24.125GHz;

bw=300MHz;

t_sweep=15mSec;

Fs=10Mhz;

Using chirp function the signal will be too large to work with.

when i tried to use functions from RadarToolbox like this:

waveform = phased.FMCWWaveform('SweepTime',tm,'SweepBandwidth',bw,...
    'SampleRate',fs,'SweepDirection','Up');

and the function does not take into account the carrier frequency

2) I could not measure the frequency shift due to range and velocity. This is my main problem. I don't understand how to extract this kind of information from the object
