MMWCAS-RF-EVM: Possibility of phase-coding a chirp.

Hi

I know, that it is possible to apply a constant Phase-Modulation value of 0/pi to the chirp. So you either have 1 or -1.

But is it also possible to phase-code a chirp? So the phase modulation is not from chirp to chirp but within a chirp?

Thanks in advance!
