Abstract
The authors present a method for measuring the temperature-depth profile in a lossy material by applying Kalman algorithm to radiometric signals. The method employs a correlation microwave radiometer. It uses both short-range weighting functions and the delay times of the correlator. An experimental verification of this new thermal inversion approach is presented. The thermal noise is received in the microwave domain, by a S band radiometer by using an automatic experimental bench. A feature of this method is that it can be used in biomedical applications.
Résumé
Les auteurs présentent une méthode de mesure de la température en profondeur dans un milieu dissipatif par application de l’algorithme de Kalman aux signaux radiométriques. Cette méthode emploie un radiomètre micro-onde à corrélation. Elle utilise des fonctions de couplage qui caractérisent le couplage entre un milieu dissipatif et une antenne, et le temps de retard du corrélateur. Une vérification expérimentale de cette nouvelle approche d’inversion thermique est présentée. Le signal de bruit thermique est traité à l’aide d’un radiomètre à bande S, en utilisant un banc expérimental automatisé. Cette méthode est destinée, en particulier, à des applications biomédicales.
