Abstract

The present invention is applicable to the communication field, and provides a target positioning method, system and detection node. The method is applied to a network architecture including several detection nodes and nodes to be positioned, including: the detection node and its area The detection node establishes a neighbor relationship with other detection nodes; the detection node obtains the measurement data shared by its neighbor detection nodes; the detection node performs decorrelation processing on the obtained measurement data and the measurement data detected by itself to obtain a processing result; the The detection node reconstructs the target position vector of the node to be positioned according to the processing result, iteratively updates and average consistency data fusion, and when the result of the iterative update meets the preset iteration termination condition, the result is used as the final positioning result of the node to be positioned . The invention can realize target positioning in a non-centralized scene, and solve the problem that the prior art completely relies on a centralized fusion center or base station, resulting in low system robustness.

Description

technical field [0001] The invention belongs to the field of communication technology, and in particular relates to a target positioning method, system and detection node Background technique [0002] Compressive Sensing (CS) technology, also known as compressed sampling technology, applies this technology to target positioning scenarios to take advantage of the natural sparsity of the target to be located in the grid space (that is, the target to be located is only in several grids). appear on the point), and achieve efficient and accurate positioning of multiple targets in the observation area through the measurement data of fewer detection nodes. [0003] However, the existing CS target positioning technology is based on a centralized scenario, that is, each local detection node reports the measurement data at its location to a centralized fusion center or base station in the scene, and then the centralized fusion center or base station according to The collected measure...
