Abstract:
Based on the analysis of analogous linear frequency modulated (chirp) signals propagation inside the ionosphere HF channel, a geometrical-optics technique for data processing at the output of LFM ionosonde compressor is proposed, allowing reconstruction of the frequency dependence of the complex reflection coefficient to the initial phase under multipath conditions. Use of the above technique will allow an increase of information capacity of the atmosphere remote LFM sensing.
