Can I use phased.Bac​kscatterPe​destrian and phased.FMCWWaveform to simulate wideband echo, like fc=77GHz, BW=4GHz?

Hi, in the example of "Introduction to micro-doppler effects"(https://de.mathworks.com/help/phased/examples/introduction-to-micro-doppler-effects.html), functions phased.BackscatterPedestrian and phased.FMCWWaveform are used to simulate the FMCW radar echo of pedestrian. I am wondering if I can set bandwidth parameter in phased.FMCWWaveform as 4GHz and fc as 77GHz, and use the same process as the example showed to generate pedestrian echo? Could someone help me to make this clear? Many thanks!

There is nothing prevents you to set the bandwidth to 4GHz. The only thing you need to be cautious is that with such a bandwidth, your sampling rate is also going to be in GHz. This means that depending on your sweep time, the memory requirement could be high.
