Problems solved by technology

Among them, the angle-of-arrival algorithm is the most commonly used. The angle-of-arrival algorithm has the characteristics of high precision and strong anti-interference. However, when the algorithm is used to deal with problems such as multipath effects, noise, received signal fluctuations, and frequency / phase changes, there are still many technologies. Difficulties need to be resolved

Abstract

The method provided by the embodiment of the invention provides a positioning method and device based on arrival angle distance measurement, and the method comprises the steps: carrying out the preprocessing of incident signal data after a receiver antenna group carries out the collection of the incident signal data based on each antenna, and constructing an initial sample matrix; then, reconstructing the initial matrix to generate a mapping sample matrix; then, after the loss of the mapping matrix is corrected, adjusting elements in the mapping matrix; and finally, selecting and calculating a phase difference between the samples through an incident angle calculation model, and then estimating the angle of an incident signal according to the phase difference. According to the method, the error of the signal and the environmental influence are corrected, so that a more accurate positioning result can be obtained.

Description

【Technical field】 [0001] The present invention relates to the field of positioning technology, in particular to a positioning method and device based on angle-of-arrival distance measurement. 【Background technique】 [0002] With the widespread application of 5G (5th Generation Mobile Networks, fifth-generation mobile communication technology) networks and IoT (Internet of Things, Internet of Things) technologies, indoor positioning will become more and more important. Indoor positioning refers to the realization of position positioning in the indoor environment. It mainly adopts wireless communication, base station positioning, inertial navigation positioning and other technologies to form an indoor position positioning system, so as to realize the position monitoring of people and objects in the indoor space. At present, the calculations widely used in the field of positioning technology include reception strength algorithm, angle of arrival algorithm, time of arrival algor...
