ADIBEAM
Abstract—the increase in navigation accuracy demanded by
EGNOS and Galileo and their future evolution encourages the
study and design of advance receiver architectures. In that
direction, the ADIBEAM project focuses on the design of high
accuracy ground stations, specifically GNSS Reference Stations, in
order to improve its robustness in front of multipath and
interference errors with the goal of achieving centimeter level
tracking accuracy. The adoption of antenna arrays and digital
beamforming at the ground reference station receivers is one of
the most promising approaches to cope with errors induced by
multipath and interference.

为了对空间辐射源进行精确定位" 建立了基于任意阵列对多目标源进行二维DOA估计的数学模型。将 MUSIC算法推广到三维空间阵列可以对辐射源进行二维高精度测向,但由于其需要估计接收数据的协方差矩阵和进行特征分解, 因而其计算量较大。利用多级维纳滤波器的前向递推获得信号子空间和噪声子空间,不需要估计协方差矩阵和对其进行特征分解,从而降低了MUSIC算法的计算量。将文中的方法应用于任意阵列的二维DOA估计中进行计算机仿真和实际侧向系统性能验证,实验结果均表明该方法达到了MUSIC算法的性能,但与常规MUSIC算法相比降低了计算量.( In order to space radiation source for precise positioning" based on arbitrary array to multiple target source 2D DOA estimation model. The MUSIC algorithm is extended to three-dimensional space to two-dimensional array of radiation source for high precision direction finding, but due to the need to estimate the covariance matrix and eigenvalue decomposition, and the large amount of calculation. Use of multistage Wiener filter forward recursion received signal and noise subspace, does not need to estimate the covariance matrix and the eigenvalue decomposition, which reduces the computation of MUSIC algorithm. This method is applied to an arbitrary array DOA estimation for computer simulation and actual lateral system performance verification, the experimental results show that this method achieves the performance of MUSIC algorithm, but with the conventional MUSIC algorithm reduces the calculation amount.)
