- 针对多径效应的影响,提出了一种基于矩阵束的MIMO 雷达低仰角快速估计方法。该方法同时考虑了发射多径信号和接收多径信号,采用单样本数信号矢量构造了一个前后向矩阵束,并利用两个酉矩阵对该矩阵束进行降维处理,最后采用广义特征值分解的总体最小二乘法来估计目标角度。算法不需要估计数据协方差矩阵,可在低 信噪比和单样本数情况下,有效地克服多径效应,实现同时多目标低仰角估计,相比最大似然算法,避免了谱峰搜索,计算量小。仿真结果验证了该算法的有效性。-To overcome the multipath e

- Multidimensional Scaling(MDS)是一种经典的数据降维方法,同时也是数据可视化的一种手段。这个问题的最早起源,是当我们仅能获得物体之间的相似性矩阵时,如何由此来重构它们的欧几里德坐标。譬如,对一个国家的许多城市而言,假如我们并不能确定它们的经纬度信息,却知道所有城市两两之间的距离,就可以通过MDS方法将这些代表相似性的距离数据,呈现在二维坐标上。-Multidimensional Scaling (MDS) is a classical data dimensionali
