摘要
基于PARAFAC技术,结合最小二乘误差准则,对三维数学模型进行求解来估计波达方向。该方法不需要进行常规MUSIC算法的谱峰搜索和ESPRIT算法的广义奇异值分解过程,对噪声形式没有严格限制。计算机仿真结果验证了该算法的可行性。
Based on PARAFAC technology,we estimate the Direction of Arrival with the least square error criteria to the 3D mathematical model.The method does not need the spectrum searching in the common MUSIC algorithm or the generalized singular value decomposition in the ESPRIT algorithm,and has no limitation to the noises.Computer simulation verifies the method.
