波束形成就是从传感器阵列重构源信号。(1)、通过增加期望信源的贡献来实现;(2)、通过抑制掉干扰源来实现。经典的波束形成需要观测方向(期望信源的方向)的知识。盲波束形成试图在没有期望信源方向信息的情况下进行信源的恢复。
波束形成技术的基本思想是:通过将各阵元输出进行加权求和,在一时间内将天线阵列波束“导向”到一个方向上,对期望信号得到最大输出功率的导向位置即给出DOA估计。
虽然阵列天线的方向图是全方向的,但阵列的输出经过加权求和后,却可以被调整到阵列接收的方向增益聚集在一个方向上,相当于形成了一个”波束”。这就是波束形成的物理意义所在。

Abstract—We propose two novel energy-aware routing algorithms for wireless ad hoc networks, called reliable minimum energy cost
routing (RMECR) and reliable minimum energy routing (RMER). RMECR addresses three important requirements of ad hoc networks:
energy-efficiency, reliability, and prolonging network lifetime. It considers the energy consumption and the remaining battery energy of
nodes as well as quality of links to find energy-efficient and reliable routes that increase the operational lifetime of the network. RMER,
on the other hand, is

MIMORadarDOAEstimation
MIMO雷达模型下一种子空间谱估计方法,采用过估计的方法,以避免信源数估计的问题,直接对数据协方差矩阵进行变换,从而构造了信号子空间投影矩阵和噪声子空间投影矩阵,不需要像经典的MUSIC一样对其进行特征分解,完全避开了在一般非理想情况下MUSIC算法必须面对的识别小特征值与大特征值的麻烦,降低了复杂度,而且该方法不受快拍数的影响,在相干源情况下也能准确的估计目标的入射角,不会出现伪峰。(A subspace based DOA (Direction-Of-Arrival) estimation method for MIMO (Multiple-Input Multiple-Output) radar is studied in this paper. By transforming the data covariance matrix, we can construct the projection matrix of signal subspace and noise subspace. The computation complexity of the algorithm is reduced as it does not need to perform eigendecomposition. By using the over estimated theory, this algorithm avoid estimating the number of signal sources and can keep a good estimate performance in the case of lower SNR (Signal-to-Noise Ratios) and multi-target. )
