摘要:

在这项工作中,我们调查的方向发现存在的传感器增益的不确定性和方向扰动的传感器阵列处理在多频率的情况下。具体地说,我们采用了一种分布式优化方案,其中纳入了一致性模型,本地代理只在网络中连接的节点之间交换信息,即,没有融合中心。数值模拟突出了所提出的并行迭代技术在统计和计算效率方面的优势。

英文摘要:

In this work, we investigate direction finding in the presence of sensor gain uncertainties and directional perturbations for sensor array processing in a multi-frequency scenario. Specifically, we adopt a distributed optimization scheme in which coherence models are incorporated and local agents exchange information only between connected nodes in the network, i.e., without a fusion center. Numerical simulations highlight the advantages of the proposed parallel iterative technique in terms of statistical and computational efficiency.
