Title (EN) METHOD AND SYSTEM FOR ENSURING ANTENNA CONTACT AND SYSTEM FUNCTION IN APPLICATIONS OF DETECTING INTERNAL DIELECTRIC PROPERTIES IN A BODY
(FR) PROCÉDÉ ET SYSTÈME POUR ASSURER UN CONTACT D'ANTENNE ET UNE FONCTION SYSTÈME DANS LES APPLICATIONS DE DÉTECTION DES PROPRIÉTÉS DIÉLECTRIQUES INTERNES DANS LE CORPS
Abstract:
(EN) In a method for determining antenna fit of at least one antenna (105) positioned outside a body (103) microwave signal(s) are transmitted from the at least one antenna (105) towards the body (103). At least the body (103) and a surrounding medium (107) have different dielectric properties. A first part of the microwave signal is first reflected and/ or scattered from the surface of the body (103) and a second other part is entering the body (103). The reflected and/or scattered microwave signal(s) are received at another antenna (105) or at the transmitting antenna (105). The received microwave signal(s) are compared to another microwave signal or a criterion. Based on the comparing, it is determined if the at least one antenna (105) is fit to the body (103) or not.
(FR) Cette invention concerne un procédé de détermination d'ajustement d'antenne d'au moins une antenne (105) placée à l'extérieur du corps (103), où un ou des signaux hyperfréquence sont transmis depuis l'antenne (105) vers le corps (103). Le corps (103) et le milieu qui l'entoure (107) ont des propriétés diélectriques différentes. Une première partie du signal hyperfréquence est d'abord réfléchie et/ou diffusée depuis la surface du corps (103) tandis qu'une seconde partie pénètre dans le corps (103). Le ou les signaux hyperfréquence réfléchis et/ou diffusés sont reçus sur une autre antenne (105) ou sur l'antenne d'émission (105). Le ou les signaux hyperfréquence reçus sont comparés à un autre signal hyperfréquence ou à un critère. Sur la base de la comparaison, il est possible de déterminer si l'antenne (105) est ajustée au corps (103) ou non.
