Abstract: In the current article, the linear array null pattern synthesis for beam forming applications is presented using the novel social group optimization algorithm (SGOA). As a part of the simulation, the circular array of 24 element length is considered with a spacing of inter-elements of 0.5 λ is considered. These patterns are synthesized for null steering and side lobe level (SLL) optimization. Strategy of designing arrays with single and multiple nulls are presented in more robust manner in which the width of the beam and SLL are also included for objectives of design.
Keywords: Beam Forming, Null Positioning, SGOA.

Scope of the Article: Reverse Engineering
