Radio altimeter system capable of operating in a dual radio altimeter system

摘要

The present invention relates to a radio system (e.g. able to be fixed to an aircraft and to provide a distance from said aircraft with respect to a surface, adapted to operate in a radio installation comprising two such dual e.g. radio systems, e.g, said radio system, e.g. comprising a generator of radioelectric wave modulated in frequency by a modulation signal comprising the ramps of the variation of frequency according to a frequency excursion defined by at least one parameter. The radio system, e.g. according to the invention comprises means (26) for obtaining an identifier making it possible to distinguish between the radio system, e.g. of the other system of radio heights of the installation is the dual, and selection means (30) of said at least one parameter defining the frequency excursion of the modulation signal as a function of the identifier obtained. The present invention also relates to a radio installation comprising two such dual e.g. radio systems (e.g.
