摘要: 针对近场源参数估计计算复杂度大的问题,提出了一种基于对称阵列结构的快速估计算法。首先通过对称阵列结构构造多项式,通过求解多项式的根得到近场源的角度信息;在距离估计的时候,结合压缩多重信号分类算法(Compressed multiple signal classification, C-MUSIC)的思想,将菲涅尔区域分为若干个子区域,通过构造噪声子空间簇的交集,得到新的谱函数,将原来整个区域搜索变换成小区域搜索,可节省运算时间。通过仿真试验验证了算法的有效性,证明该算法的运算复杂度与传统估计算法相比得到了很大改善。

Abstract: The complicated computation has always been a serious problem in the parameter estimation of near-field sources. Based on the symmetrical array structure, a new computational efficient method for Range-of-Arrival (ROA) estimation of near-field sources is proposed. First, the polynomial is constructed through the symmetrical array structure, and the angle information of the near-field sources is obtained by solving the roots of the polynomial. Estimation of the range information is combined with the idea of compressed multiple signal classification (MUSIC). Dividing the Fresnel range into sub-intervals, the new spectral function is obtained by constructing the intersection of these noise sub-spaces. Thus, the range search is carried out in the small area instead of the whole area, which reduces the processing time. Simulation results show that the performance of the proposed algorithm is better than that of existing algorithms.

Key words: communication technology, near-field source estimation, symmetrical array structure, compressed multiple signal classification(C-MUSIC), root multiple signal classification(R-MUSIC)
