A Three-Dimensional Parameter Estimation Method of Near Field Sources Based on Second Statistics
一种基于二阶统计量的近场源三维参数估计方法

In this paper, the problem of the frequency, bearing and range estimate in near field is considered. Only using second statistics and corresponding pairing program, the proposed algorithm can estimate parameters. The method does not need spectral peak searching, and can avoid using fourth-order cumulant, reduce calculating burden. The effectiveness of the method is demonstrated through some simulation examples.
