摘要 该文研究近场源的距离、角度和频率的三维参数估计问题。提出了一种仅需利用二阶统计量和相应的配对程序就能直接估计出参数的新方法。该方法无需谱峰搜索,同时避免应用四阶累积量,减轻了算法的计算量。仿真实验证明了该算法的有效性。 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.
