    I am developing an application based on the pulse-doppler matrix using the example matlab code provided with the module connector. The plot shows the 'Doppler frquency [RPM]' on the X axis, but I am not quite sure how the interpret the doppler data. Breathing (respiration) appears in the plot as a more-or-less symetric peak with center and 0 frequency. How does this represents a respiration pattern?
