Intelligent Wi-Fi imaging method and system based on field programmable meta-material

Abstract

The invention discloses an intelligent Wi-Fi imaging method and system based on a field programmable meta-material. An intelligent Wi-Fi imaging system based on a field programmable meta-material is built by adopting a Wi-Fi router, a reference receiver, a main receiver and an electric control field programmable meta-material with a working frequency band covering a Wi-Fi frequency band. The method comprises the steps that: a Wi-Fi signal is directly used for detecting a target, electromagnetic waves do not need to be actively emitted to the target, and a deep learning method is used for achieving long-distance and non-line-of-sight real-time imaging on the target. The intelligent Wi-Fi imaging method and system can achieve long-distance and non-line-of-sight real-time imaging, and have the characteristics of low cost, high efficiency and the like.

Description

technical field

[0001] The invention belongs to the cross technical fields of artificial intelligence, artificial electromagnetic materials and electromagnetic imaging, and relates to microwave electromagnetic imaging technology, in particular to an intelligent Wi-Fi imaging method and system based on deep learning and field programmable metamaterials. Background technique

[0002] With the rapid development of modern information technology, microwave has been widely used in the perception and monitoring of the surrounding unknown environment due to its characteristics of wireless propagation and strong penetration, and can realize long-distance and non-line-of-sight target detection and recognition. It has greatly extended the sensory functions of human beings themselves. Among them, microwave electromagnetic imaging is a detection technology that uses microwaves to obtain target geometric parameters and electrical parameters. Currently, it has extremely important applicati...
