Hi Kasper,
unfortunately with the Sense2GoL platform it is not possible to operate FMCW modulation for two reasons
1. Microcontroller used does not have a DAC to drive the ramp
2. The port for tuning voltages on the RADAR MMIC (VTUNE) currently is fixed by HW to the temperature output of the chip to keep the MMIC in CW mode. This one would be the one that needs to be driven by a DAC
Thus, to conclude Sense2GoL was developed as a Doppler Radar Chip. FMCW operation is not possible without HW changes.
Best regards,
Thomas
