摘要

多径信号是测向系统参数估计误差的主要来源。本文提出了一种分两步估计远场源到达方向(DOA)和近场多径反射定位的新方法。首先,利用标定技术估计远场源的DOA。第二步,提出近场到远场的变换,消除阵列数据中的远场分量,只获取近场信号分量来估计近场多径信号。该方法采用均匀圆阵对远场信号进行二维DOA估计,采用虚拟均匀线阵结构对近场多径信号进行位置估计。采用理想和接近真实世界的数据集对所提出的方法进行了评估。结果表明,该方法能有效地估计远场和近场源参数。

Direction finding and localization for far-field sources with near-field multipath reflections
Multipath signals are main source of error for parameter estimation in direction finding applications. In this paper, a new method is proposed for the estimation of direction-of-arrivals (DOA) of a far-field source and localization of its near-field multipath reflections in two steps. Firstly, far-field source DOA is estimated using a calibration technique. In the second step, a near-to-far field transformation is presented in order to eliminate the far-field components of the array data and obtain only near-field signal components to estimate the near-field multipath signals. The proposed method uses uniform circular array in order to give 2D DOA estimation for far-field signal and virtual uniform linear array structure is used in order to estimate locations of the near-field multipaths. The proposed method is evaluated using both ideal and close-to-real world data sets. It is shown that far and near-field source parameters are effectively estimated.
