In applications such as seismic acquisition, the position information of sensor nodes, that are deployed in a linear topology, is desired with sub-meter accuracy in the presence of a limited number of anchor nodes. This can be achieved with antenna arrays via mm-wave cooperative localization, whose performance limits are derived in this letter. The number of anchor nodes is seen to have a stronger impact than the number of antenna elements in the anchor nodes. Succinct closed-form expressions for the position error bound are also obtained for 1-hop and 2-hop cooperative localization, where sub-meter accuracy is perceived over several hundred nodes.

线性拓扑中毫米波协同定位的基本性能限制

在地震采集等应用中，在存在有限数量的锚节点的情况下，需要以线性拓扑部署的传感器节点的位置信息具有亚米级精度。这可以通过毫米波协作定位使用天线阵列来实现，其性能限制在这封信中得出。锚节点的数量被认为比锚节点中天线单元的数量具有更大的影响。还为 1 跳和 2 跳协作定位获得了位置误差界限的简洁封闭形式表达式，其中在数百个节点上感知到亚米级精度。
