基于和声搜索-凸优化混合算法对新型四维圆阵的优化设计与综合
Optimal design and synthesis of a novel 4-D circular array based on harmonic search-convex optimization algorithm
摘要
Abstract
Four-dimensional(4-D)circular array with elements uniformly excited is designed and synthesized.First,by utilizing rotationally symmetric structure,the array geometry and the time modulation of the time-modulated sparse circular array is proposed.Radiation pat-terns in time domain and frequency domain are formulated and analyzed.Then,in order to obtain the desired radiation pattern at the operating frequency and suppress the sideband ra-diation,the synthesis problem is established and solved by the proposed harmony search-convex programming algorithm.Finally,two experimental examples are presented and opti-mized.The numerical results indicate that the time-modulated sparse circular array with ro-tationally symmetric structure has the advantages of superior performance,such as low peak sidelobe level,suppressed sideband level,two-dimensional null in specified direction,and improved directivity.关键词
