System for radiolocalisation, especially for tracking trajectories of meteorological balloons

摘要

The present invention relates to a radiolocation system comprising converters (300) on board the mobile objects and at least one ground station designed to process the converted signals received from the converters (300), characterised in that the converters (300) comprise a frequency conversion stage (310) controlled by a local oscillator (308) and means (310) designed to superimpose on the signal retransmitted by each on-board repeater (310) an nth harmonic from the local oscillator (308) used.
