Challenges to national defence in contemporary geopolitical situation

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.

The most notable machines that currently have the impact of eliminating humans from direct contact with the enemy are various types of remotely controlled or autonomous drones. They wreak havoc and fear in the enemy camp, significantly affecting the outcome of current conflicts. The fact of increasing the advantage in the attack causes the need for adequate defense or rescue measures. Thus, the use of remote-controlled drones for rescue/medical purposes seems a natural or even necessary path for the development of military technology. The described drone is intended to be unmanned, designed to transport only one injured person to be evacuated from an area of intense combat with the usage of an onboard robot. It is intended that the drone will be electrically powered which will reduce the possibility of detection due to acoustic and heat signature.
