Radio system capable of operating in a multiple radio altimeter system

摘要

The system (22) has a radio wave generator for generating a frequency modulated radio wave by a modulation signal comprising a repetition of sequences of variation of frequency. The successive sequences are separated by a waiting level with variable duration. An identifier obtaining module (26) distinguishes the system from any other radio altimetry installation. A generation module (30) selects a configuration of the waiting level for the modulation signal according to the identifier, where the configuration of the waiting level defines variable durations of the waiting level.
