FMCW add-on: Catching Movements with a Simple Arrangement of Range-FFT, Threshold and PPI (Video)

In this short video we visualize movements of a person in front of a training radar. We apply range FFT, source suppression, a threshold and a PPI. We also look at the movements in an A-Scope.

Video: FFT Plot of a Pulsed Doppler Radar Implemented with SkyRadar's NextGen Radar and FreeScopes

This article features a video on an FFT plot. It has been implemented in real-time, just by connecting and calibrating the blocks in the block-diagram. The video shows well how the FFT amplitude moves to the right, when the person approaches and to the left when the person moves away from the source.

Why is the FFT Plot of a pulsed-Doppler radar mirrored? (Video)

When it comes to radar, the FFT (Fast-Fourier Transform) is used to convert time domain signals into frequencies. An example of its use is for converting the dual channels of a pulse-Doppler radar from time domain into range-Doppler data.
