METHOD FOR REMOTE DETECTION OF THE SEA STATE BY HIGH FREQUENCY RADAR

Abstract

Abstract Translated from French METHODE POUR LA TELEDETECTION DE L'ETAT DE LA MER PAR DETERMINATION DU SPECTRE DE FREQUENCE DES ECHOS SUCCESSIFS SUR LES VAGUES D'IMPULSIONS DE RADAR A HAUTE FREQUENCE TRANSMISES SEQUENTIELLEMENT. ELLE COMPORTE LA MESURE DE LA RAIE DE BRAGG LA PLUS IMPORTANTE, LA MESURE D'UNE RAIE DU SPECTRE DU 2 ORDRE DONT LA FREQUENCE EST PROPORTIONNELLE A CELLE DE LA RAIE DE BRAGG MESUREE, ET LA DETERMINATION DU RAPPORT DE CES DEUX MESURES. APPLICATION EN PARTICULIER A LA MESURE DE LA HAUTEUR SIGNIFICATIVE DES VAGUES. METHOD FOR REMOTE DETECTION OF SEA STATES BY DETERMINATION OF THE FREQUENCY SPECTRUM OF SUCCESSIVE ECHOES ON SEQUENTIALLY TRANSMITTED HIGH FREQUENCY RADAR PULSE WAVES. IT INCLUDES THE MEASUREMENT OF THE MOST IMPORTANT BRAGG RAY, THE MEASUREMENT OF A SPECTRUM RAY OF 2 ORDER WHOSE FREQUENCY IS PROPORTIONAL TO THAT OF THE MEASURED BRAGG RAY, AND THE DETERMINATION OF THE RATIO OF THESE TWO MEASURES. APPLICATION IN PARTICULAR TO MEASURING SIGNIFICANT WAVE HEIGHT.
