This paper presents an implementation of pattern synthesis method for conformal arrays, to suppress the side-lobe level in the array, where the excitation coefficients are computed for a conformal array, from the array pattern. The process involved concentrates on the development of a GUI that is meant to form a generic means to obtain excitation coefficients to be applied to the array. The pattern from the GUI forms a base of comparison to the pattern that is resulting from the simulation. The pattern synthesized for a 40 element array which is a sector of a circular array, based on the coefficients generated, achieves suppressed side-lobe level of 34dB considering the 15dB of suppression, provided by direct implementation of Taylor distribution, with a gain of 22dB. © 2020 IEEE.
