Optimizing and Thinning Planar Array Using Chebyshev Distribution and Improved Particle Swarm Optimization

Noor Salem Alshdaifat, Mohammed Hussein Bataineh.

Abstract
In this paper, a new approach to the optimum solution based on the Chebyshev distribution for planar array and an improved particle swarm optimization (IPSO) will be considered.The current excitation of each element is used as the optimization factor with an aim to suppress the side lobe level (SLL) and reduce the half power beam width (HPBW) with prescribed nulls. Chebyshev distribution is used to define IPSO search space. The same array is then thinned to find the best distribution of the active, or on, elements in order to obtain the desired requirements.

Key words: Planar Array; Chebyshev Distribution; Improved Particle Swarm Optimization; Side Lobe Level Suppression, Half Power Beam Width.
