Problems solved by technology

[0007] However, this type of technique is still complex because it typically requires storing long-term signals that include a large number of frequencies to ensure reliable comparisons
Despite this resource-intensive learning, this technique is sensitive to changes in the medium and inaccuracies of previously saved signatures

Embodiment Construction

[0087] The invention relates to a method for detecting and / or locating and / or identifying receivers in a medium, in particular by transmitting / receiving waves in this medium. This wave is called a primary wave and can be electromagnetic, acoustic or vibratory in nature.

[0088] For the sake of simplicity, the invention will be described primarily in the application of electromagnetic waves, in particular of the wireless transmission type, such as:

[0089] - transmission of electromagnetic energy, or

[0090] - GSM, 3G, 4G, 5G mobile phone service, or

[0091] - WiFi, Bluetooth type wireless network, or

[0092] - the network between connected objects,

[0093] e.g. iOT, or

[0094] - RFID type tag reader, or

[0095] - Any other wireless transmission between devices having a wireless connection via radio waves.

[0096] However, the invention is applicable to any wave frequency domain.

[0097] The method is for example via figure 1 System 1 schematically represented...

Abstract

A method is disclosed for determining a detection characteristic of a receiver and / or an identity information and / or location information on a receiver (20), in which: (a) a primary wave is emitted byan antenna, (b) adjustable elements are controlled with a plurality of sets of parameters in order to modify the propagation of a primary wave and / or secondary wave from the receiver, (c) signals received by the antenna are recorded, and (d) the characteristic of the receiver in the medium is determined from the signals received for each set of parameters.

Description

technical field [0001] The invention relates to a method and a system for determining a characteristic of a receiver in a medium, said characteristic being detection information and / or identification information and / or position information of said receiver. Background technique [0002] More specifically, the invention relates to a method for detecting, identifying or locating receivers by propagating waves in a medium. [0003] There are many methods for these applications. [0004] For example, according to a first technique for detecting / locating objects in a medium, antenna arrays are conventionally used either by mechanical rotation of a directional beam antenna or by tilting by means of delay and amplitude weights on multiple antenna elements beam (beamforming technique) to scan an area of ​​the medium. In addition, the position of the object is determined by the receiving antenna by estimating the angle of arrival and time-of-flight of the secondary wave reflected b...
