ALTIMETRY RADIO SYSTEM ADAPTED TO OPERATE IN A DUAL ALTIMETRY RADIO INSTALLATION

摘要

The invention relates to a radio altimetry system capable of being fixed to an aircraft and of providing a distance from said aircraft with respect to a surface, adapted to operate in a dual radio altimetry installation comprising two such radio altimetry systems, said radio navigation system. radio altimetry device comprising a radio frequency wave generator modulated in frequency by a modulation signal comprising ramps of frequency variation according to a frequency deviation defined by at least one parameter. The radio altimetry system according to the invention comprises means (26) for obtaining an identifier making it possible to distinguish said radio altimetry system from the other radio altimetry system of said dual installation, and selection means (30). ) of said at least one parameter defining the frequency deviation of the modulation signal according to the identifier obtained. The invention also relates to a dual radio altimetry installation comprising two such radio altimetry systems.
