In today’s post, I will show you how to perform a two-dimensional Fast Fourier Transform in Matlab. The 2D Fourier Transform is an indispensable tool in many fields, including image processing, radar, optics and machine vision. In image processing, the 2D Fourier Transform allows one to see the frequency spectrum of the data in both dimensions and lets one visualize filtering operations more easily. In radar, the 2D Fourier Transform is used as a fast way to create a map from a series of coherent radar pulses. Additionally, the far-field pattern of a 2D antenna can be calculated using a 2D Fourier Transform. In Fourier Optics, the 2D Fourier Transform is used to calculate the propagation of electromagnetic waves and through space and optical elements. Continue reading
