Abstract

The paper presents a comprehensive algorithm to calculate characteristics of backscatter signals (BS) within the waveguide approach. The algorithm input parameters are profiles of electron density and effective frequency of collisions that are calculated from IRI model, electric parameters and the earth surface scattering coefficient. Based on the comprehensive algorithm, one can calculate amplitude characteristics of BS signals, including the signal time base using angular coefficients of radio wave scattering from rough surface. Simulation is performed for given two-way antenna-feeders. We implemented real-time algorithms to determine the BS signal leading edge and the skip zone border. Results of simulating signal characteristics are used to analyze and interpret BS ionograms obtained from the chirp ionosonde of the Institute of Solar-Terrestrial Physics SB RAS.
