A beacon transmission signal comprises at least one carrier (C+SB) including sidebands (SB) and one sideband only signal (SBO), said carrier and said signal being in any mutual phase relationship. The method of the invention includes the steps of demodulating the sum of the carrier (C+SB) and of the signal (SBO), on one hand by multiplying it by a frequency (F), and on the other hand by multiplying it by the same frequency in phase quadrature, extracting from the products continuous components representative of the carrier portion (C) of said carrier (C+SB) and the low frequency components of the beacon transmission signal representative of the sideband portions (SB) of the carrier (C+SB) and of the signal (SBO), calculating the module and phase of portion (C) of the carrier (C+SB) and deriving from the low frequency components the amplitudes of the sidebands (SB) and the amplitude and phase of the signal (SBO).

L'émission de la balise est composée d'au moins une porteuse (P+BL) comprenant des bandes latérales (BL) et d'un signal (BLS) à bandes latérales seules, cette porteuse et ce signal ayant des relations de phase quelconques. Suivant l'invention on démodule la somme de la porteuse (P+BL) et du signal (BLS) par multiplication d'une part avec une fréquence (F) et, d'autre part, avec cette même fréquence en quadrature de phase, on extrait de ces produits les composantes continues représentatives de la partie (P) de la porteuse (P+BL) et les composantes aux fréquences basses de l'émission de la balise représentatives des parties (BL) de la porteuse (P+BL) et du signal (BLS), on calcule le module et la phase de la partie (P) de la porteuse (P+BL), et on déduit des composantes aux fréquences basses l'amplitude des bandes latérales (BL) et l'amplitude et la phase du signal (BLS).
