Abstract

Artillery is the main means of defeating enemy launchers in modern combat. According to estimates, artillery in the confrontation with Russia accounts for 70 to 80% of all losses suffered by the parties to the conflict.
The effectiveness of artillery fire is ensured by a single automated radar complex for reconnaissance of firing positions and unmanned aerial vehicles (UAVs).
The exchange of information between the ground and air components of the complex, the transmission of data to the automated fire control system takes place through interference-protected communication channels using signal repeaters placed on the UAV.
The mathematical models developed in the work made it possible theoretically and experimentally, through simulation modeling, to evaluate the effectiveness of using the proposed new and improved known methods of synthesis of hardware to ensure communication with the necessary reliability of information transmission.
Phase and frame synchronization devices were developed on the basis of a modernized phase auto-frequency adjustment scheme, which reduced the time of entering into synchronism and increased the tracking band, significantly increased the quality of signal demodulation and the immunity of communication channels in conditions of complex interference conditions. This made it possible to implement an experimental sample of the proposed anti-interference communication system.

Keywords: interference-immunity; modulation-demodulation; artillery reconnaissance; telemetry information; relaying signals.
