I am having some trouble wrapping my head around setting up the ADF4159 ramp settings. My goal is to be able to arrange some settings so I can create capture data within from 0-10 m from my device.
I am feeding the ADF4159 from a ADF5901 with a 12.125 GHz. In the data sheet's FMCW radar ramp settings worked example, there were (arbitrary?) values provided for 50 MHz range over 2 ms, PFD frequency of 25 MHz, and hop frequency of 250 kHz. Does anyone have some insight as to why these values were selected? How does this effect the range?
