Abstract—A method based on Fast Fourier Transform for detecting the position and the level of fault in antenna arrays, from the degraded far field pattern samples is proposed. The paper considers Chebyshev array of specified side lobe level as a desired antenna pattern and authors develop strategy to test on it. The paper also deals with several different combinations of failures and successfully detects using the proposed technique, which takes lesser computational time than other optimization algorithms. In this paper, the method is developed and applied to a linear array of isotropic antennas; however, the principle can easily be extended to other type of arrays.
