21	Agent-based target detection in 3-dimensional environments Correia, J. Steve. 03 1900 (has links) Approved for public release, distribution is unlimited / Visual perception modeling is generally weak for game AI and computer generated forces (CGF), or agents, in computer games and military simulations. Several tricks and shortcuts are used in perceptual modeling. The results are, under certain conditions, unrealistic behaviors that negatively effect user immersion in games and call into question the validity of calculations in fine resolution military simulations. By determining what the computer-generated agent sees using methods similar to that used to generate the human players' screen view in 3- D virtual environments, we hope to present a method that can more accurately model human visual perception, specifically the major problem of a entity "hiding in plain sight" / Lieutenant, United States Navy Artificial intelligence Military applications Visual perception War Computer simulation Visual programming (Computer science) Perceptual modeling Target detection Artificial intelligence Non-player characters Synthetic players
22	Battle damage assessment using inverse synthetic aperture radar (ISAR) Lim, Kian Guan 12 1900 (has links) Approved for public release; distribution in unlimited. / An imaging radar, like ISAR, offers a combatant the capability to perform long range surveillance with high quality imagery for positive target identification. Extending this attractive feature to the battle damage assessment problem (BDA) gives the operator instant viewing of the target's behavior when it is hit. As a consequence, immediate and decisive action can be quickly taken (if required). However, the conventional Fourier processing adopted by most ISAR systems does not provide adequate time resolution to capture the target's dynamic responses during the hit. As a result, the radar image becomes distorted. To improve the time resolution, time-frequency transform (TFT) methods of ISAR imaging have been proposed. Unlike traditional Fourier-based processing, TFT's allows variable time resolution of the entire event that falls within the ISAR coherent integration period to be extracted as part of the imaging process. We have shown in this thesis that the use of linear Short Time-Frequency Transforms allows the translational response of the aircraft caused by a blast force to be clearly extracted. The TFT extracted images not only tell us how the aircraft responds to a blast effect but also provides additional information about the cause of image distortion in the traditional ISAR display.

23	Bradford Non-Lethal Weapons Research Project (BNLWRP). Research Report No. 6. Davison, N., Lewer, N. January 2004 (has links) yes / New non-lethal technologies (weapons and delivery systems) continue to make the news, both for their civil and military applications. Technologies which were considered to be in the realm of science fiction a few years ago, are now beginning to undergo field trials or, in some cases, are being deployed with police and soldiers on active service. As this, and our previous reports have highlighted, the development of acoustic weapons (Long Range Acoustic Device) and microwave weapons (Active Denial System) have proceeded rapidly as have advances in robotic, unmanned vehicles for the delivery of both lethal and non-lethal weapons. We repeat our concern that there is a danger of these new non-lethal technologies being `rushed¿ into service (1) without thorough testing for harmful health effects, (2) without a deeper consideration of civil and human rights, (3) without full discussion of their impact on arms control treaties and conventions, and (4) without further study of their social and cultural impact. Since many such weapons will have a rheostatic capacity along the non-lethal to lethal continuum, it is important that weapons developers and manufacturers, and those charged with the responsibility of using them, are held clearly accountable and have transparent rules of engagement. Of particular concern are a new generation of biological and chemical weapons. With respect to the health impact, NATO has a panel working on NLW human effects, the Human Factors and Medicine (HFM) Panel 073, which is due to report later this year (2004) on the Human Effects of Non-Lethal Technologies.1 Non-lethal weapons Civil and military applications Long Range Acoustic Device Acoustic weapons Microwave weapons Robotic, unmanned vehicles Harmful health effects Civil and human rights Impact on arms control conventions Social impact
24	Bradford Non-Lethal Weapons Research Project (BNLWRP). Research Report No. 4. Davison, N., Lewer, N. January 2003 (has links) yes / Non-lethal weapons (NLWs) are explicitly designed and primarily employed to incapacitate personnel or material whilst minimising collateral damage to property and the environment. Existing NLWs include rubber and plastic bullets, entangling nets, chemical sprays such as OC and CS gas, and electrical stunning devices such as the `Taser¿ gun. New NLWs are on the way, which will include acoustic and microwave weapons, non-lethal landmines, malodorants, and sophisticated weapons developed through rapid advances in neuroscience and the genomics revolution. Most analysts would agree that there is a `legitimate¿ role for non-lethal weapons, both for civil and military applications. However there is considerable disagreement as to the operational effectiveness of NLWs, and the threat such weapons pose to arms conventions and international law. As usual, a balance has to be achieved where the benign advantages of developing and deploying non-lethal weapons are not outweighed by their more malign effects. In particular, emerging non-lethal technologies offer an increasing opportunity for the suppression of civil dissent and control of populations ¿ these are sometimes referred to as the `technologies of political control¿. There is a continuing need for sustained and informed commentary to such developments which highlights the impact and threats that these technologies pose to civil liberties and human rights. Because the last BNLWP Report was produced in August 2001, this edition is somewhat longer than usual so that key developments since then can be highlighted and summarised. Future BNLWRP reports will be published three times a year, and we welcome material to be considered for inclusion.

25	Autonomous agent-based simulation of an AEGIS Cruiser combat information center performing battle air-defense commander operations Calfee, Sharif H. 03 1900 (has links) The AEGIS Cruiser Air-Defense Simulation is a program that models the operations of a Combat Information Center (CIC) team performing the ADC duties in a battle group using Multi-Agent System (MAS) technology implemented in the Java programming language. Set in the Arabian Gulf region, the simulation is a top-view, dynamic, graphics-driven software implementation that provides a picture of the CIC team grappling with a challenging, complex problem. Conceived primarily as a system to assist ships, waterfront training teams, and battle group staffs in ADC training and doctrine formulation, the simulation was designed to gain insight and understanding into the numerous factors (skills, experience, fatigue, aircraft numbers, weather, etc.) that influence the performance of the overall CIC team and watchstanders. The program explores the team's performance under abnormal or high intensity/stress situations by simulating their mental processes, decision-making aspects, communications patterns, and cognitive attributes. Everything in the scenario is logged, which allows for the reconstruction of interesting events (i.e. watchstander mistakes, chain-of-error analysis) for use in post-scenario training as well as the creation of new, more focused themes for actual CIC team scenarios. The simulation also tracks various watchstander and CIC team performance metrics for review by the user. / Lieutenant, United States Navy Artificial intelligence Military applications AEGIS (Weapons system) Battle Group Air-Defense Multi-Agent Systems Artificial Intelligence Air-Defense Commander Naval Simulations Combat Information Center Air-Defense Simulation AEGIS, Cruiser CG, Human-Computer Interface (HCI) Watchstander Training Naval Air Defense Threat Assessment Decision Making Cognitive Factors AEGIS Doctrine, Air-Defense Doctrine Interactive Training Systems Watchstander Fatigue Link-16/TADIL J Link-11/TADIL A USS Vincennes
