Abstract

Abstract

The entangled photon positioning method is one of the current research hotspots in the field of navigation and positioning. However, the existing methods consider rarely the influence of the dynamic changes of the scattering environment on the performance of propagation distance estimation in different light sources, resulting in the problem of low positioning accuracy and poor robustness. To solve this problem, an entangled light quantum positioning method is proposed based on adaptive light source selection. First of all, the mathematical relationship between the interference of different scattering environments and the light propagation distance in each light source is established, the average photon loss rate of each light source signal light time pulse sequence is calculated, and the time pulse sequence of each light source is dynamically grouped. Then, the optical time pulse sequence is matched, and the propagation distance of each light source in each group is obtained according to the second-order correlation curve of light. Finally, based on the relative error of each light source in each group, the light source with the smaller relative error in each group is dynamically selected for positioning. The experimental results show that the proposed method has high positioning accuracy and strong positioning robustness.
