Book excerpt: CETTE THESE PRESENTE UNE ETUDE EXPERIMENTALE REALISEE DANS LA GRANDE SOUFFLERIE DE SIMULATION DES ECHANGES AIR-MER DE L'I.M.S.T AVEC LE DIFFUSIOMETRE RAMSES 2 DU C.N.E.S. AFIN DE PRECISER LES MECANISMES DE RETRODIFFUSION DES HYPERFREQUENCES A LA SURFACE DE LA MER. UNE REVUE CRITIQUE DES CONNAISSANCES ACTUELLES EN MATIERE DE DYNAMIQUE DES VAGUES ET DE MODELES DE RETRODIFFUSION PAR LES SURFACES RUGUEUSES A D'ABORD ETE EFFECTUEE. ELLE FOURNIT LES ELEMENTS QUI PERMETTRONT AUX NON SPECIALISTES DE L'UN OU L'AUTRE DES DEUX DOMAINES CONCERNES D'APPREHENDER DE FACON GLOBALE LE PROBLEME DE L'INTERPRETATION DES DONNEES DE TELEDETECTION HYPERFREQUENCE EN TERME DE PARAMETRES OCEANO-METEOROLOGIQUES ET D'EVALUER LES MOYENS SUSCEPTIBLES D'APPORTER DE NOUVELLES SOLUTIONS. LA PROCEDURE EXPERIMENTALE MISE EN OEUVRE EST ENSUITE DECRITE. ELLE REPOND A L'OBJECTIF PRINCIPAL D'IDENTIFICATION DE PHASE DES MOUVEMENTS DE LA HOULE ET DES VAGUES QUI CONTRIBUENT DE MANIERE SIGNIFICATIVE A LA RETRODIFFUSION DES HYPERFREQUENCES, EN ASSOCIANT DES INSTRUMENTS TRES PERFECTIONNES DE MESURE DE LA TOPOGRAPHIE (HAUTEUR ET PENTES) DE LA SURFACE. LES SIGNAUX REFLECHIS, A 13.6 ET 5.3 HZ, AU VOISINAGE DE L'INCIDENCE VERTICALE POUR DIVERSES COMBINAISONS SIMPLES ET COMPLEXES DE HOULES ET VAGUES DE VENT SONT ANALYSES. LES RESULTATS PRINCIPAUX CONCERNENT: A) L'EXISTENCE D'UN NIVEAU DE REFLEXION PLUS IMPORTANT DANS LES CREUX QUE SUR LES CRETES DE LA HOULE ET L'IMPORTANCE DES CONDITIONS D'ILLUMINATION; B) LE ROLE PREDOMINANT DU DEFERLEMENT DANS LA REFLEXION PAR LES TRAINS DE HOULE; UNE INTERPRETATION ORIGINALE EST PROPOSEE; C) L'INFLUENCE SUR LA REFLEXION DE LA PRESENCE D'OSCILLATIONS DE COURTES LONGUEURS D'ONDE LE LONG DES PROFILS DE LA HOULE; D) LA NECESSITE DE PRENDRE EN COMPTE LA STRUCTURE TRIDIMENSIONNELLE DES CHAMPS DE VAGUES GENERES PAR LE VENT ET LE CARACTERE IMPULSIF DU SIGNAL RETRODIFFUSE MEME LORSQUE LA TACHE AU SOL COUVRE PLUSIEURS LONGUEURS D'ONDE DES VAGUES. LES EXPERIENCES COMPARATIVES REALISEES AU WALLOPS SPACE FLIGHT CENTER AVEC UN SYSTEME FOCALISE ET NON FOCALISE CONFIRMENT LES OPERATIONS PRECEDENTES. DISCUSSION DES IMPLICATIONS DE CES RESULTATS POUR LA POURSUITE DE TRAVAUX COMPLEMENTAIRES

Available in PDF, EPUB and Kindle. Book excerpt: Microwave Imaging Methods and Applications provides practitioners and researchers with a complete overview of the latest and most important noninvasive and nondestructive techniques for inspecting structures and bodies by using microwaves. Placing emphasis on applications, the book considers many areas, from medical imaging and security… to industrial engineering and subsurface prospection. For each application, readers are presented with the objectives of the inspection and related challenges. Moreover, this groundbreaking resource details computational methods that can be used to solve inverse problems related to specific applications. Including clear examples or the most significant practical results, this forward-looking reference focuses on systems that have been recently developed. Professionals gain the knowledge needed to compare imaging methods used in different applications and develop new uses of imaging apparatuses and systems.
