Abstrakt: Intelligence as a warfighting function is a continuous process. It is carried out before planning the mission, during the preparation of the mission, and during its execution as well. The results of the intelligence warfighting function enable commanders to predict the course of action for potential threats and facilitate the commander´s decision-making process. If intelligence information is derived from foreign communication (Communication Intelligence) and noncommunication (Electronic Intelligence) electromagnetic radiations by other than intended recipients, we are speaking about Signals Intelligence. Communication and noncommunication foreign emitters might be also denoted as Radio-Electronic objects. This paper presents an algorithm for analysis of some relevant energetic proportions of a skywave propagation, with consideration of Electronic Intelligence in the high-frequency band. In terms of Electronic Intelligence, Radio-Electronic object is represented by the Over-The-Horizon radar.

Kľúčové slová: Electronic intelligence; Radio-electronic object; Over-the-horizon radar; Energetic proportions; High-frequency band.

Abstrakt: Resolution measurement of the night branch of the mounted device is investigated in this article. Measuring optical parameters of a mounted devices is a real problem that can improve the overall battle performance and effectivity of the armoured vehicle. The experimental verification is designed to be performed in field conditions with accessible equipment. To measure the resolution, it is needed to design corresponding test targets. To protect image intensifier from damage, it is necessary to use protection cover which attenuate incoming illumination. With decreased illumination the resolution of the imager also decreases, this hypothesis is demonstrated on experimental measurement.

Abstrakt: This work is performed by tribotechnical diagnostics, specifically by checking the properties of motor oil type Mogul Diesel DT SAE 20W-50 used in heavy combat equipment, such as the T-72M1 tank. The work consists of expressing basic knowledge about measuring devices, which were used in the measurements and their properties and their operation. The work also contains basic knowledge about the measured liquid, which is a necessary aspect for the possibility of performing measurements. The practical part of this work consists of measurements and more detailed specification of oil properties and monitoring of its gradual degradation with the help of individual measuring instruments. All measurements were performed in the diagnostics laboratory of the Department of Mechanical Engineering at the Armed Forces Academy of General Milan Rastislav Štefánik (hereinafter„AFA”) in Liptovský Mikuláš.
