Abstract
Μέθοδος για την παρακολούθηση ενός αντικειμένου η οποία περιλαμβάνει τη δημιουργία, στη γειτονιά του παρακολουθούμενου αντικειμένου, ενεργειακών πεδίων πολλαπλών διαφορετικών συχνοτήτων και τη λήψη σημάτων τα οποία παράγονται σε μία θέση του αντικειμένου, λόγω ανταπόκρισης στα ενεργειακά πεδία των διαφορετικών συχνοτήτων. Με βάση τα λαμβανόμενα σήματα διαφορετικών συχνοτήτων, πραγματοποιούνται επαναλαμβανόμενοι υπολογισμοί των χωρικών συντεταγμένων του αντικειμένου. Προκειμένου να διαπιστωθεί αν τα ενεργειακά πεδία έχουν διαταραχθεί, λόγω της παρουσίας κάποιου ξένου (μεταλλικού) σώματος στη γειτονιά του παρακολουθούμενου αντικειμένου, ελέγχεται αν οι παραπάνω υπολογισμοί δίνουν συγκλίνοντα αποτελέσματα.
