Estimation of the Transfer Ratio Frequency Characteristic of HF Radio Channel by Using the LFM Signal

摘要

A technique for determining the transfer ratio frequency relationship of a short-wave ionospheric radio channel with high resolution has been considered using the continuous linear-frequency-modulated signal. This technique is based on the filtering of modes of ionospheric propagation at the receiver output following the compression method processing in the frequency domain. The estimates of measurement errors were also presented.
