Section III shows the conventional FMCW radar detection algorithm using the 3D FFT. In Section IV, we present the structure of the proposed algorithm.
However, in order to perform a 3D FFT, very high complexity is required, as is well known.

Our 2D FFT accelerator was used to calculate the 2D FFTs of the projections as well as for initial stages of the 3D FFT which was then completed on the host PC.
Compensate the propagation losses, and reduce the coupling and noises beyond the region of interest by range gating, and then the compensated signal is upsampled along the y- and z-axes through zero-padding to avoid any aliasing, followed by transforming to the 3D Fourier domain via a 3D fft.
