X axis is the sample number.

In the picture a measurement using the default modulation over a wall about 3m distance from radar is shown. Considering that the time to get 2048 samples with the default modulation is 3,471ms and we can see about 16 periods of the sinusoidal signal this means that the dominant sinus shown below is about 4,609KHz frequency. The frequency of the IF radar signal is proportional to the distance from the radar to the target (in this case the wall).
