Abstract : HF backscatter sounders offer the perspective of real-time sensing of ionospheric radio propagation conditions in an extended area. However, to this data, difficulties are experienced with the interpretation of sounding data, which places a severe limit on the operational use of these sounders. The French National Telecommunications Research Centre is constructing a sounder of original design. We evaluate the new possibilities for data interpretation offered by this system and discuss possible operational implications.
