== Understanding What is Time domain signal ==

The time domain signal window shows the 2048 samples captured of the IF radar signal on the last measurement. The  Y axis represents the signal voltage and the . 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 this means that the dominant sinus shown 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).
