Title (EN) RADAR SYSTEM AND METHOD FOR LOCATING AND IDENTIFYING OBJECTS BY THEIR NON-LINEAR ECHO SIGNALS
(FR) SYSTÈME RADAR ET PROCÉDÉ POUR LOCALISER ET IDENTIFIER DES OBJETS PAR LEUR SIGNAUX D’ÉCHO NON LINÉAIRES
Abstract:
(EN) The invention relates to a harmonic radar system which comprises: (a) at least two transmitting units for simultaneously, and in synchronization transmitting electromagnetic radiation in distinct frequencies f1, f2,f3 … towards a space of interest; and (b) at least one receiving unit tuned to a frequency of nf1 mf2+qf3... , wherein n,m,q… being integers not equal to zero, for receiving a non-linear response of said radiation from objects located within the said space of interest.
(FR) L’invention vise un système radar harmonique qui comporte : (a) au moins deux unités de transmission pour transmettre de façon simultanée et synchrone des rayonnements électromagnétiques sur différentes fréquences f1, f2, f3… vers un espace à observer ; et (b) au moins une unité de réception accordée à une fréquence de nf1 mf2+qf3... , n, m, q… étant des entiers non nuls, pour recevoir une réponse non linéaire desdits rayonnements venant des objets situés dans ledit espace à observer.
