Pattern Synthesis for Planar Array Based on Elements Rotation
Aiming at improving the radiating characteristics (pattern and polarization) and simplifying the design of feeding network, a new approach is applied and discussed. For uniformly excited planar antenna array, by rotating each element in its local coordinates and determining the rotation angles of the elements, the 3D radiating characteristic of the planar antenna array can be improved. The Diff...
متن کاملA Clonal Selection Algorithm for Array Pattern Nulling by Controlling the Positions of Selected Elements
In this paper, a method based on clonal selection algorithm (CLONALG) is proposed for null steering of linear antenna arrays by controlling only the positions of selected elements. The CLONALG is a relatively novel population-based evolutionary algorithm inspired by the clonal selection principle of the human immune system. In order to illustrate the accuracy and flexibility of the proposed alg...
متن کاملSAR Image Segmentation Based On Hybrid PSOGSA Optimization Algorithm
Image segmentation is useful in many applications. It can identify the regions of interest in a scene or annotate the data. It categorizes the existing segmentation algorithm into region-based segmentation, data clustering, and edge-base segmentation. Region-based segmentation includes the seeded and unseeded region growing algorithms, the JSEG, and the fast scanning algorithm. Due to the prese...
متن کاملArray Pattern Control and Synthesis
Antenna array distributions and their associated patterns are now designed on physical principles, based on placement of zeros of the array polynomial. An overview of the synthesis processes is given. Robust and low Q distributions for linear arrays and circular planar arrays, that provide variable side lobe level pencil beam patterns, are treated in detail. Associated difference patterns are i...
متن کاملAn Arbitrary Conformal Array Pattern Synthesis Method That Includes Mutual Coupling and Platform Effects
The research in the paper puts forward a novel method for synthesizing conformal arrays and optimizing low cross-polarizations including the effects of elements mutual coupling and mounted platform. Starting from the far-field superposition principle, an efficient approach with active element pattern technique is proposed to calculate the far-field patterns. A coordinate transform is used to cr...
