Two complex ground-space experiments to study effects of acoustic perturbations on the ionosphere were conducted in Ukraine in 2013—2014. The analysis of the obtained data together with experimental data of previous years gave a new knowledge on the influence of a low-frequency sound (including an infrasound) on the upper atmosphere and ionosphere and opened the perspective fields of further researches. We used in these experiments the DEMETER and «Chibis-M» satellites in an orbital segment, and a ground-based low-frequency acoustic emitter LFAE (Lviv Center of Space Research Institute of NASU and SSAU) and the URAN-3 radio telescope (Karpenko Physico-Mechanical Institute of NASU, Lviv) in the ground segment. Analysis of the obtained data allows us to conclude that there are periodic and aperiodic variations in their statistical characteristics as well as correllation between the manifestation of the effect and the arrival of an acoustic wave to the ionosphere. At first the physical and mathematical models and novel numerical algorithm were developed for modeling of LFAE’s radiation propagation from the ground to the ionosphere, which take into account real parameters of the environment. The advanced scheme of further combined ground-space acoustic experiments is offered.
