一种低计算复杂度的球面稀疏阵列优化算法
An Optimization Algorithm for Thinned Spherical Arrays with Low Computation Complexity
摘要
Abstract
The high computation complexity of traditional optimization algorithms has a strong impact on engineering realization for thinned spherical arrays.In this paper,an optimization algorithm with low complexity for thinned array is presented based on conformal half⁃spherical arrays. Elements are located fully at the middle of the spherical arrays, and located uniform randomly at the other positions.Further,the number of layers with full arrays is optimized through computer simulation. The results show that the proposed algorithm can effectively reduce the side lobe level,and the optimized arrays are still symmetrical about the center of the spherical surface.关键词
