ElectronicsIn this paper, to obtain antenna arrays with grating lobes suppression capability in wideband and achieve a low peak sidelobe level (PSLL), two non-uniform spiral antenna arrays and an enhanced Harris Hawks optimization (EHHO) algorithm are proposed.

Sidelobe Suppression of Polyphase Coded Signal Using Different Filters
Journal of Engineering and Sustainable Development, 2012 This paper deals with different types of polyphase coded signals in terms of their correlation properties. The (Frank, P1, P2, P3 and P4) polyphase codes and the Iterative Reweight Least Square(IRLS) procedure were used in this work. Each polyphase code
