Problems solved by technology

[0003] However, the CS target positioning technology completely relies on the centralized processing center in the positioning system, and is only suitable for target device positioning in a centralized scenario. When faced with a non-centralized scenario without a centralized processing center, the CS target positioning technology will not be able to In addition, when the observation area is large or the radiation power of the target equipment is small, resulting in non-global reachability of the radiation signal of the target equipment, the accuracy and effectiveness of the CS target positioning technology will also be seriously affected

Abstract

An embodiment of the invention relates to the technical field of communication, and discloses a target device positioning method and related equipment in a non-centralized scene. The method and the related equipment have no centralized processing center in a positioning system, when a radiation signal of a target device is not globally reachable (i.e., the radiation power of the target device is relatively small or the overall observation area is relatively large), on the premise of not increasing the total number of detection nodes in the positioning system, and by using the potential low-order characteristics of a target location matrix built by unknown target location vectors to be solved between adjacent cluster nodes and the average consistency of signal rebuilding information between the adjacent cluster nodes, accurate and efficient positioning of the target device in the non-centralized scene is realized.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for locating a target device in a decentralized scenario and related devices. Background technique [0002] At present, Compressive Sensing (CS) target positioning technology is mainly used in such as figure 1 In the centralized scenario shown, all local detection nodes report the measurement data at their respective locations to a centralized processing center (that is, fusion center or base station) in the positioning system, and the centralized processing center The measurement data reconstructs the position vector of unknown target devices (such as mobile phones, smart terminals, etc.), and locates the position coordinates of the target devices in the observation area according to the reconstruction results. [0003] However, the CS target positioning technology completely relies on the centralized processing center in the positioning system, and is o...
