What Is Azimuth Fourier Transform in Signal Processing?

Click For Summary
SUMMARY

The Azimuth Fourier Transform (AFT) is a specialized application of the Fourier Transform used in signal processing, particularly in the context of electromagnetic waves and antenna theory. It operates in the spatial domain, specifically utilizing polar coordinates rather than Cartesian coordinates. The Inverse Azimuth Fourier Transform serves as the counterpart to AFT, allowing for the reconstruction of signals from their frequency components. Understanding AFT is crucial for analyzing directional properties of signals in various applications, including radar and communications.

I am reading something about Electromagnetic wave and Antenna, and come across some equations that the author says are "Azimuth Fourier Transform" and "Inverse Azimuth Fourier Transform". While I am somewhat familiar with Fourier Transform in the time/frequency domains, "Azimuth Fourier Transform" really is something I see the first time and I am not sure from the geometry why they are defined that way. Have anyone seen anything like this and can point me to some more detail information? Is it just a special case of Fourier Transform in the spatial domain rather in time domain?

Perhaps the article you read is referring to calculating the Fourier transform in Polar coordinates..:-p instead of cartesian ones.
