In the study of radiation source positioning, there are some positioning errors about the target node based on the Angle of arrival (AOA) measurement method. On this basis, how to effectively use the information between nodes to improve positioning accuracy has been a research hotspot. This paper uses two nodes as an example. Using the range information between two nodes to conduct a one-dimensional angle search can determine the position coordinates of two nodes on the plane. Aim to improve the Direction Finding (DF) and positioning accuracy of a single node by using the distance between two adjacent nodes. The experimental results show that the proposed positioning method effectively improves the positioning accuracy of a single node.
