The air defence missile system effective coverage determination using computer simulation

One of the most important prerequisites, for successful air-defence and its combat activities, is knowledge of the missile system effective coverage. There is a need to know related zones too. But determination all of them by standard - empirical methods is quite expensive. This article deals with the possibility to determine an effective coverage using mathematical modelling and computer simulation for air-defence missiles guidance process.

Conceptual operational architecture of the air force simulator: Simulation of air defense operations

Expensive live training together with the evolution of information technologies gives a great opportunity to build a military simulation centers with high level of realism. To train not only one sort of the force (like pilots or drivers only) we have to merge simulation capabilities to single robust simulation environment with the ability to train wide spectrum of personnel together. However to do so, it is necessary to solve lots of key problems of forces coordination and cooperation. This paper proposes the concept of air force simulator operational architecture.

Simulation of surface-to-air missile units: Cluster design

Today military simulations state of the art systems require the high level of implemented reality into the models. These models of military equipment should be realistic not just in case of visualization but also in case of behavior. Surface-to-air missile systems are very sophisticated systems that comprise capabilities of platform itself, its sensors, weapon system (missile), capability to act together with other similar entities at the battlefield, etc. This article deals with certain aspects of surface-to-air missile systems modeling and simulation - modelling of cluster design.

Simplification of missile effective coverage zone in air defence simulations

Military modelling and simulation plays a key role in troops training as well as in verification of military scenarios. Most of topics in the modelling of military performance were already successfully implemented into the simulators (like troops moving, fighting, aircraft simulation, etc.) however the simulation of surface (ground) based air defence systems capabilities are not fully developed now. For last five years, Department of Air Defence Systems, University of Defence Brno, has been experimenting with different approaches to modelling of missile systems firing capabilities. This paper is based on one approach how to simulate these capabilities and deals with the simplification of missile systems effective coverage zones for the easier implementation into the military simulators.

Multi-agent system as operational center support

Civilian or military operational centers are typical for their specific set of activities according to solved problems. Operational personnel have to perform procedural as well as positive kind of control of its controlled entities. To help these personnel with their decisions, we propose to build an automated system based on knowledge structure. This paper deals with procedural reasoning multi agent system designed to take over certain kind of task at operational center like firefighting operational center or military air operations center.

Evaluation Methodology and Measurement of Physiological Data to Determine Operational Preparedness of Air Defense Staff: Preliminary Results

The aim of the article is to introduce new evaluation methodology to determine operational preparedness of air defense staff based on measurement of physiological data. The individuals working with air defense systems are under very high level of stress and long‐term monotone air picture observation workload during the mission. We designed an experiment and a method of measuring the biomedical signals for monitoring the actual operator condition during long‐term work on air picture simulator that shows real‐time aircraft flight information. Long‐term monitoring and recording of potential airborne targets in the area of interest to which operators are subjected is accompanied by monitoring the physiological data such as heart rate, body temperature, movement activity and perspiration intensity of operators. The proposed methodology and measurements were tested on four air defense system operators of the Army of the Czech Republic. Operators took part in a 4‐h intensive measurement without any break and their training was evaluated. Designed methods could help to monitor, on the base of physiological data and data from simulators, the stress load level and operational preparedness.

Physiological Data Monitoring of Members of Air Forces During Training on Simulators

Many complex situations can be induced to the members of air forces during training on simulators, which may result in mentally vigorous situations or even overload. The aim of the paper is to describe the current state and our contribution to development of systems for measurement of the physiological data of basic member of air force including mission commander, pilots, air traffic controllers and ground support staff. The reason for physiological data monitoring is to test the possibility of usage them to estimate the physical and psychological state of the team members. The base for the design of physiological data monitoring was the FlexiGuar system, originally developed at the FBMI CTU. The core of simulators for training of military personnel in aviation was Lockheed Martin’s Prepar3D simulation software. Two airplane cockpits were used as simulators for training of two pilots, air traffic control simulator, i.e. a control tower simulator, and an airport ground station for the preparation of aviation ground staff. The proposed systems are used for simultaneous measurement of the working performance and physiological data of members of the four‐member team during their training. The physiological data, heart rate, body temperature, movement activity and perspiration intensity, are transferred to the commander visualization unit for further evaluation. Designed systems and methods could help to monitor, on the base of physiological data and data from simulators, the stress load of team members.

Semiportable Manually Actuated System for Measuring Muscle Spasticity

In the article, we describe a design of a new system which provides means to quantitatively assess passive resistance of skeletal muscles, also termed muscle spasticity. New design is focused on the measurement of muscle groups which are responsible for movement of elbow joint. The semiportable system is an alternative to expensive motorized isokinetic dynamometers. System is manually actuated dynamometer. The electronic subsystem of the system is used to measure angular velocity and torque in the elbow joint. An incremental encoder is used for the measurement of angular velocity. The angular velocity of the rotational movement in a joint is a result of movement effected by manually controlled lever. The lever is controlled by a physician. During the angular movement of the upper limb segments, the elbow joint torque is measured by a strain gauge subsystem. The output from the system is a graphic dependence between the angular velocity and the torque, which is used to evaluate spasticity. The dependence between the passive moment of force and kinematic angular parameters allows us to study complex motion and force possibilities of the joint. The designed system could be useable and widely applicable in clinical practice, as well as research of diseases and treatment of musculoskeletal system.

P 160 - Non-linear analysis of trunk movement of air defense staff: Pilot study

Measurements of acceleration of a persons body segment by wearable MoCap system is one of the most important tool to investigate a movement activity. However, the aim of our study is to assess the ability of the trunk movement activity assessment by non-linear method to identify and differences in traffic density and hours of shift work. Poincaré plot with five minute intervals in four hour length data was used to calculate the standard deviations SD1 and SD2. Also, air traffic density with five minute intervals in four hour length data was calculated. The results show that SD1 reflects the short-term variability, and SD2 reflects both short-term and long-term variability. The statistically significant differences found on SD1 values of different hours is the most important finding and indicates that the short-term variability of trunk movement activity is changing during hours of shift work. On the other hand, the traffic density does not have influence on SD. An explanation for this is that motion activity does not change with higher workload, but longer work activity does. Therefore, these findings and the proposed method can be used to optimize the duration of work shifts and working breaks of Air Defense Staff members.

Countering UAVs – the Mover of Research in Military Technology

Unmanned aerial vehicles (UAVs) are massively seeping into a wide range of human activities. Along with other remotely controlled or automatic devices, they have entered many aspects of human activities and industry. While the majority of researchers have been working on the construction, deployment and non-military use of UAVs, the protection against UAVs remained on the edge of their interest. Nowadays, the situation is rapidly changing. The risk of misuse of UAVs by criminals, guerrillas or terrorists has compelled authorities, scientists and defence industry to face this threat. Organisations have launched crucial infrastructure defence programs to cope with UAV threat. To solve this problem, it is necessary to develop disciplines improving the air space surveillance and UAVs elimination techniques. The substantial aspects of the UAVs detection and elimination were analysed, being supported by a number of conferences, workshops and journals articles. The contribution of the study in the Counter–UAV area consists particularly in generalisation and evaluation of the main technical issues. The aim of this paper is to emphasise the importance of developing new scientific fields for countering UAVs, and hence it is directed firstly on the scientific audience.
