论文摘要
在这项工作中，我们研究了在有传感器的不确定性和方向性扰动中，在多频场场景中处理的方向发现。具体而言，我们采用了分布式优化方案，其中合并了连贯的模型，而本地代理仅在网络中连接的节点之间（即没有融合中心）之间进行交换信息。数值模拟在统计和计算效率方面突出了所提出的平行迭代技术的优势。
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.
