Circular antenna array design method based on quantum particle swarm optimization for aperture synthesis radiometers
摘要
Abstract
Sparse antenna array design is of great importance in aperture synthesis radiometers. Due to the non-redundant baseline distribution and the simplicity of mechanical structure, the circular antenna array is considered as a promising array configuration of aperture synthesis radiometers. In this paper, a circular antenna array design method based on quantum particle swarm optimization （QPSO） is proposed to improve the UV coverage of the circular antenna array in aperture synthesis radiometers. By introducing quantum mechanics and constructing a novel measure function of UV coverage, this method outperforms the existing methods in terms of the computation complexity and global exploration efficiency, and has a better measurement for the uniformity of UV coverage. Numerical simulations validate the effectiveness of the proposed method.关键词
