| 摘 要： | 针对非正侧视阵在俯仰向抑制近程杂波时算法效果不佳的问题,文中提出了一种基于特征空间自适应波束形成的近程杂波抑制算法。该算法对俯仰空域协方差矩阵进行特征分解,分离出近程杂波的支撑特征向量,并将其作为约束进行自适应波束形成。该算法对阵元误差具有鲁棒性,并克服了一般自适应滤波难以实现方向图保形的缺点。仿真结果证明了该算法的有效性。 |

| Abstract: | Currently developed methods do not perform well for short-range clutter suppression of non-side-looking arrays.This paper presents an algorithm based on eigenspace adaptive beamforming technique.This algorithm performs eigen-decomposition of the spatial covariance matrix and extracts the short-range clutter support eigenvectors.The eigenvectors are then used as constraints for adaptive beamforming.This algorithm is robust to element errors.Furthermore,it overcomes the pattern reshaping problems of conventio... |
