Array pattern synthesis using flower pollination algorithm

Abstract

In this paper, Synthesis of sum patterns to generate narrow beams with reduced sidelobes using Flower Pollination Algorithm is presented. The array design is first formulated as an optimization problem with the goal of reducing peak sidelobe level to −50dB. The objective of the FPA algorithm is to determine the optimized set of amplitude excitation coefficients to obtain the desired pattern. The patterns are numerically computed for different array lengths and the results obtained are compared with those of conventional method in the present paper. These low side lobe patterns are useful to overcome EMI problems in radar system.
