Amplitude Distribution Synthesize of Unequally Spaced Arrays

In this paper, we study two different methods, called Legendre and LMS, to find the current distribution of an unequally spaced array structure. In both methods, we aim to find the most similar radiation pattern to a desired one toward an arbitrary angle and then show the ability of LMS method to provide the low SLL (Side Lobe Level) comparing to Legendre method due to its better performance for minimizing error.
