Radio altimetry system adapted to operate in a dual radio altimetry installation

摘要

Radioaltimetry system suitable to be fixed to an aircraft and to provide a distance of said aircraft from a surface, adapted to operate in a dual radioaltimetry installation (2) consisting of two such radioaltimetry systems, said radioaltimetry system consisting of a frequency modulated radio wave generator by a modulation signal consisting of frequency variation ramps according to a frequency excursion defined by at least one parameter, consisting of means (26) for obtaining an identifier that allows distinguishing said radioaltimetry system of the other radioaltimetry system of said dual installation (2), and selection means (30) of said at least one parameter defining the frequency excursion of the modulation signal according to the identifier obtained, characterized in that Obtaining an identifier is carried out during commissioning. nto and because the frequency excursion is defined by a predetermined frequency variation value ΔF and by a sense of positive or negative variation associated with the frequency variation ramps, said parameter defining said direction of variation.
