The embodiment of the invention provides a target positioning method, a target positioning device and a target positioning system, relates to the field of communication and aims to improve the positioning accuracy of the target positioning system. The target positioning method is applicable to a network architecture. The network architecture comprises a positioning device, at least two detection devices and at least two cluster head devices. The method comprises the following steps that: each cluster head device acquires measuring data of a target device, which are detected by each detection device in a management range of each cluster head device; each cluster head device de-correlates the measuring data to acquire cluster head data; and each cluster head device sends the cluster head data to the positioning device, so the positioning device performs joint sparse processing on the cluster head data to acquire target position data and determines the position of the target device according to the target position data. The target positioning method, the target positioning device and the target positioning system provided by the embodiment of the invention are applicable to positioning of the target device.
Description
technical field [0001] The present invention relates to the communication field, in particular to a target positioning method, device and system. Background technique [0002] Wireless positioning technology is a technology to obtain the position of the target device by measuring and processing the position parameters carried in the radio waves sent to the target device. When there are multiple target devices in the system, multi-target positioning is required. The entire target positioning system can be regarded as a grid space. CS (Compressive Sensing, compressed sensing) technology, also known as compressed sampling technology, utilizes the target device in the The natural sparsity in the grid space, that is, the target device only appears on several grid points, and multiple target devices in the target positioning system can be located through the measurement data of less detection devices. However, in the prior art, the target positioning system using CS technology re...
