Challenges to national defence in contemporary geopolitical situation

This paper presents deterministic and stochastic matrix models for radiophysical processes in UAV microcontroller systems. The methodology generalizes matrix signal dynamics using Markov switchings and Ornstein–Uhlenbeck diffusion approximation. Based on oscilloscope measurements of the power supply voltage, model parameters were identified, revealing increased fluctuation intensity under higher propulsion loads. The results enable quantitative stability assessment of control algorithms. The key contribution is the combination of the matrix modeling approach with experimental identification of stochastic parameters under realistic electromagnetic interference conditions.

The paper presents a hybrid methodological framework for resolving military capability gaps by integrating Multi-Criteria Decision-Making (MCDM) and constructive simulation. The purpose is to enhance defense planning transparency and objectivity. Using the Analytic Hierarchy Process (AHP), expert-driven criteria weights were established, focusing on force protection and operational effectiveness. These were validated via 200 stochastic simulation cycles in MASA SWORD, comparing conventional reconnaissance against UAV-integrated structures. Findings indicate that UAV integration (OCE = 0.7882) provides a 50.6% reduction in friendly fatalities compared to traditional methods (OCE = 0.6945). The framework offers a scalable, auditable tool for evidence-based strategic procurement.

The study aims to increase amplitude direction-finding sensitivity for radio monitoring. The methodology utilizes a TSA antenna and a phase-antiphase divider to form dual radiation patterns. Results confirm high accuracy and signal processing speed. The originality lies in combining a compact design with an innovative processing algorithm. Practical value is demonstrated by a small-scale UAV-integrated finder capable of intercepting ultra-weak signals for reconnaissance and EW. The paper establishes a universal approach to high-efficiency mobile defense systems with low power consumption.
