Hello, I am trying to improve my spatial resolution using the X4M300 by shortening the pulse width. It's not quite clear to me how to directly change the pulse width from the documentation provided. I know there is a finite number of phase bins, however, I seem to get a wide baseband signal when a person is present. Some other types of objects can appear to have a higher amplitude, but a more narrow baseband signal. I can increase the Dac_min value and I see what appears to be a big change for the better in target separation and less noise. I can also raise dac min to almost the dac max value and almost completely squash out the signal. This leaves me with a couple questions. Which X4 register can I use to change the pulse width or duty cycle of the pulsed radar? What are the pros and cons of adjusting dac_min? Best Regards, Jameson PS. I posted this in the X4300 Forums, but I realize that It actually applies more to the X4 SoC.
