Development of a Surface-to-Air Missile T&E Federation

Lucas, Jason L., Kent, Robert A. 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper focuses on the development of the Surface-to-Air Missile Federation (SAM Fed), a Test and Evaluation (T&E) High Level Architecture (HLA) federation. The SAM Fed evolved from a legacy constructive real time/post mission hardware-in-the-loop (HITL) Surface-to-Air Missile (SAM) simulation. The process to transition from a standalone simulation to a distributed HLA federation as well as the problems experienced and lessons learned will be presented. This paper will also discuss the merit of standardizing internal federate interfaces to facilitate reuse.

Nytt luftvärnssystem för Sverige : Patriot eller Aster SAMP/T?

Wannehag, Jim January 2017 (has links)
Till följd av Försvarsmaktens tidigare inriktning mot insatsförsvar och den strategiska time-out som präglade början av 2000-talet förfogar luftvärnet idag över luftvärnssystem som är flera decennier gamla. Systemen är inte dimensionerade för att möta dagens högteknologiska motståndare och regeringen har därför beslutat att en ersättare till Robotsystem 97 skall vara på plats senast 2020. Valet står mellan Patriot och Aster SAMP/T, syftet med detta arbete är därför att undersöka och bedöma den militära effektiviteten för respektive luftvärnssystem. Undersökningen baseras på en komparativ analys där luftvärnssystemen jämförs utifrån ett scenario med tillhörande händelseförlopp och kravställningar. Slutligen sammanställs och presenteras resultatet i en multimålmodell för att på ett kvantitativt sätt kunna mäta skillnaderna mellan systemen. Resultatet visar på att Aster SAMP/T har störst potential att vara effektivt i en given kontext men att Patriot också uppfyller de krav som ställs nästintill utan begränsning. Då jämförelsen grundar sig på ett begränsat scenario med specifika förutsättningar är det viktigt att ha i beaktande att resultatet endast har validitet mot det scenario och kravställningar som luftvärnssystemen jämförts utifrån. / As a result of the Swedish Armed Forces previous focus on international operations and strategic timeout in the beginning of the 21st century, the air defense today has surface-to-air missile systems that are several decades old. The systems are not designed to handle today’s high-tech opponent and the government has therefore decided that a replacement for MIM-23 HAWK must be in place by 2020. The choice stands between Patriot and Aster SAMP/T, the purpose of this paper is therefore to investigate and assess the military effectiveness of each surface-to-air missile system. The survey is based on a comparative analysis where the systems are compared to each other in a scenario which includes several events and requirements. Finally, the results are compiled and presented in a multi-goal-model to quantitatively measure the differences between the systems. The result shows that Aster SAMP/T has the greatest potential of being effective in a given context, but that Patriot also meets the requirements almost without any limitations. As the comparison is based on a particularly limited scenario with very specified conditions, it is important to take into account that the result is valid only against the scenario and requirements from which the systems are compared.

Survivability enhancement in a combat environment

Seow, Yoke Wei. 12 1900 (has links)
Approved for public release, distribution is unlimited / The objective of this thesis is to provide an aircraft with an optimal route to its destination that avoids encroaching into surface-to-air weapons killing envelopes in real time. The optimal route computed will be updated dynamically, depending on the location of the vehicle and the location of the Surface to Air Missile (SAM) sites. The problem was solved using heuristic algorithms instead of the conventional Dijkstra's & Bellman Ford algorithms, which are computationally expensive. Data fusion techniques such as spatial correlation and triangulation algorithms are presented in detail. Such techniques are important for situational awareness in a real time combat environment. Important information provided by onboard sensors are merged with the preplanned data to provide the operator with a better integrated picture of the combat environment. / Civilian, Singapore Ministry of Defense

Design, Modeling, Guidance And Control Of A Vertical Launch Surface To Air Missile

Tekin, Raziye 01 September 2010 (has links) (PDF)
The recent interests in the necessity of high maneuverability and vertical launching triggered namely the unconventional control design techniques that are effective at high angle of attack flight regimes. For most of missile configurations, this interest required thrust vector control together with conventional aerodynamic control. In this study, nonlinear modeling and dynamical analysis of a surface to air missile with both aerodynamic and thrust vector control is investigated. Aerodynamic force and moment modeling of the presented missile includes the challenging high angle of attack aerodynamics behavior and the so called hybrid control, which utilizes both tail fins and jet vanes as control surfaces. Thrust vector and aerodynamic control effectiveness is examined during flight envelope. Different autopilot designs are accomplished with hybrid control. Midcourse and terminal guidance algorithms are implemented and performed on target sets including maneuverable targets. A different initial turnover strategy is suggested and compared with standard skid-to-turn maneuver. Comparisons of initial roll with aerodynamic and thrust vector control are examined. Afterwards, some critical maneuvers and hybrid control ratio is studied with a real coded genetic algorithm. Rapid turnover for low altitude targets, intercept maneuver analysis with hybrid control ratio and lastly, engagement initiation maneuver optimization is fulfilled.
