Title
(EN) METHOD OF MEASURING IN-MEDIUM DIELECTRIC CONSTANT IN ELECTROMAGNETIC PROBER, AND ELECTROMAGNETIC PROBER
(FR) PROCEDE DE MESURE DE CONSTANTE DIELECTRIQUE INTRA-MILIEU DANS UN TESTEUR ELECTROMAGNETIQUE ET TESTEUR ELECTROMAGNETIQUE CORRESPONDANT
Abstract
(EN)
An electromagnetic prober comprising a transmission antenna, a reception antenna, a reception signal processing unit for generating an analyzing signal based on a detection signal by the reception antenna, and an analysis processing unit for performing a specified analysis processing based on the analyzing signal, wherein the analysis processing unit is provided with an in-medium dielectric constant calculating means that divides an analyzing signal into a plurality of time ranges and performs a specified computation on the average cycles of the analyzing signal in respective time ranges to thereby calculate the average dielectric constants of the medium within the depth ranges of the medium corresponding to respective time ranges, whereby enabling even an unskilled person to easily measure a dielectric constant at each depth of the medium and a depth down to an object of probing.

La présente invention concerne un testeur électromagnétique comprenant une antenne d'émission, une antenne de réception, une unité de traitement de signal de réception servant à produire un signal d'analyse en se basant sur un signal de détection issu de l'antenne de réception, et une unité de traitement d'analyse servant à réaliser un traitement d'analyse spécifié en se basant sur le signal d'analyse. Selon l'invention, l'unité de traitement d'analyse comprend un élément de calcul de constante diélectrique intra- milieu qui sert à subdiviser un signal d'analyse en une pluralité d'intervalles de temps, et à réaliser un calcul spécifié sur les cycles moyens du signal d'analyse dans des intervalles de temps respectifs, afin de calculer les constantes diélectriques moyennes du milieu à l'intérieur des intervalles d'épaisseur du milieu correspondant à des intervalles de temps respectives, ce qui permet, même à une personne non qualifiée, de réaliser facilement une mesure de la constante diélectrique pour chaque épaisseur du milieu et une épaisseur en dessous vers un objet de test.
