Application of iterative fast Fourier transform for fault finding in linear array antenna with various fault percentage

Abstract

In this paper, the detection of faulty elements in a linear antenna array with different combination of faulty element; is presented. The task of finding faulty element position and its level of fault in antenna arrays has been solved by using Iterative Fast Fourier Transform (IFFT) technique. A Chebyshev antenna array of 30 elements with specific sidelobe level (SLL) is considered as the basic antenna array and the developed formulation is tested on it. Various combinations of failure have been considered in this work and successfully detected using the developed methodology. All the Simulated results has been explained, tabulated and presented with different figures successfully.
