Challenges to national defence in contemporary geopolitical situation

The growing presence of asymmetric threats require effective C-UAS systems. This study addresses the challenge of integrating sensors (RF and EO/IR) onto multirotor platforms while maintaining flight endurance. Of the four scenarios developed, it analyzes Use-case B in detail, mathematically comparing six variants of hardware modifications to a heavy drone during reconnaissance of a 300×300 m area against both active and radio-silent targets. The results reveal the paradox of SWaP limits: fully equipped "All-in-One" platforms excel against active targets thanks to rapid guidance but face critical battery depletion during area-wide reconnaissance of autonomous threats. For future research, therefore, cooperation among multiple platforms, reduced energy consumption, and the integration of effectors are proposed.

This article proposes the application of a closed-loop algorithm for electronic warfare means intended to counter analog FPV-UAV video channels. The system-level contribution is the integration of SDR-based radio monitoring, signal-parameter estimation, OSD-assisted classification, selective multi-frequency interference scheduling, and post-action channel monitoring within one information cycle. The individual detection and interference techniques are not claimed as new; the proposed contribution lies in their coordinated control logic and feedback transitions. A conditional-probability model and a response-time model are used to describe error propagation and delay. Because no comparative field-test or simulation dataset is reported, the expected gains in efficiency and response time remain hypotheses for future validation. The approach is presented as a conceptual basis for adaptive SDR systems.
