Simulation Study of Volumetric Models of Delay Parameters of Wideband HF Radio Signals on Radio Links of Various Lengths

Paper presents a technique for calculating the integrated power delay profile of a wideband HF radio channel. Studies focused on the ionospheric radio links. The specific objective of the research were the dependences of the areas of a priori uncertainty of the average delay and the delay window on the path length and geophysical factors. An algorithm for maintaining synchronization of terminals of the SDR chirp ionosonde.
