A novel approach using Differential Evolution (DE) is proposed for linear array failure correction. In presence of the failure of array elements, only the inter-element spacing's between the array elements are adjusted to regain the pattern closed to the original one. The proposed approach is a cost effective method as no additional attenuators or phase shifters are required. A fitness function has...
A novel methodology for strategic selection of different components of PV-wind hybrid system is presented here. The optimal sizing determination is a key factor for pre-feasibility and feasibility analysis of hybrid system for any specific site. The capacity of battery, diesel generator (DG) and converter is determined with this novel approach ensuring a low cost reliable system with zero load rejection...
In several applications such as wireless communication, radar; shaped beam patterns are used to radiate power in a desired sector of region while suppressing the power towards the other direction to avoid interferences. This paper introduces a new technique to synthesizing flat-top shaped power pattern in time-modulated unequally spaced linear arrays (TMUSAs). Since, TMUSA synthesis problems are multimodal,...
In this paper, a cosecant squared shaped beam pattern is synthesized from a uniformly spaced but nonuniformly excited linear antenna array where the uniform spacing of the array elements is considered as half of the desired signal wavelength. The shaped beam pattern is synthesized for the angular beam width of 32° by reducing the side lobe level (SLL) to −20.06 dB and almost without any ripple in...
