In this algorithm, the direction-of-arrival is assumed to be a discrete random variable with a priori probability density function defined on a set of candidate points. Whether or not the secondary sample is required is based on the a posteriori probability distribution of a set of candidate point"s, which can be calculated from the array received signals. And then, the resulting beamformer is a weighted sum of the beamformers pointed at the latest set of point"s, which are combined according to the value of the a posteriori probability for each pointing direction.
在该算法中,期望信号的波达方向被看作是一个定义在若干候选波达方向上的离散随机变量,由阵列接收信号计算出各候选波达方向的后验概率,并将后验概率的分布作为是否需要进行二次采样的判断标准;随后,对各波达方向上的波束成形权值线性加权,便可得到自适应波束成形器,权系数为各候选波达方向的后验概率值。

We will demonstrate the specification of reference prior distribution on the random covariance matrix. We will consider the approximate uniform shrinkage prior and approximate Jeffreys' prior. Both are formulated based on the approximated likelihood function. Under generalized linear mixed models, we show that the posterior mode under Jeffrey's prior is asymptotically closer to the REML estimate than the mode under uniform shrinkage prior does.
