论文摘要
在诸如地震采集之类的应用中，在有限数量的锚点节点存在下，需要以次级精度为单位的传感器节点的位置信息。这可以通过天线阵列通过MM-Wave合作定位来实现，其性能限制是在这封信中得出的。锚节点的数量比锚节点中的天线元件的数量更强。对于1-HOP和2-HOP合作定位，还获得了绑定位置误差的简洁闭合表达式，其中在几百个节点上可以感知子米精度。
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.
