In this video we visualize the movement of a Fidget Spinner (hand-held toy) with the 8 GHz Pulse Radar, a Fast Fourier Transformation and a Heatmap in FreeScopes

The following video explains in detail the 2 Dimensional CFAR.

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.

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.

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.
