Hello @ronnief1,

Keeping in context with Infineon's BGT60TR13C 60GHz FMCW radar, the frequency is ramped from 58GHz to 63.5GHz.

Best Regards,

Hello @ronnief1,

For a 60GHz radar sensor wavelength will be 5mm where as for 24GHz radar wavelength is 1.25cm. As frequency increases wavelength decreases so as the penetration power. High Frequency signals cannot penetrate through walls where as low frequency signals(3KHz-1GHz) can as their wavelengths are high. For a FMCW radar, maximum range which a radar can detect a target is depended on the range resolution which is again depended on bandwidth.

Thanks. If my radar has a 60HGz frequency, then how does that frequency change during the modulation?

And these values cannot be changed?

Hello @ronnief1,

Yes, you're not supposed to change.
