Approved for public release, distribution is unlimited / The United States Navy requires radical and innovative ways to model and design multifunction phased array radars. This thesis puts forth the concept that Genetic Algorithms, computer simulations that mirror the natural selection process to develop creative solutions to complex problems, would be extremely well suited in this application. The capability of a Genetic Algorithm to predict adequately the behavior of an array antenna with randomly located elements was verified with expected results through the design, construction, development and evaluation of a test-bed array. The test-bed array was constructed of commercially available components, including a unique and innovative application of a quadrature modulator microchip used in commercial communications applications. Corroboration of predicted beam patterns from both Genetic Algorithm and Method of Moments calculations was achieved in anechoic chamber measurements conducted with the test-bed array. Both H-plane and E-plane data runs were made with several phase steered beams. In all cases the measured data agreed with that predicted from both modeling programs. Although time limited experiments to beam forming and steering with phase shifting, the test-bed array is fully capable of beam forming and steering though both phase shifting and amplitude tapering. / Outstanding Thesis / Lieutenant Commander, United States Navy

I en tid då Försvarsmakten brottas med hög personalomsättning av soldater står Luftvärnsregementet i Halmstad inför en ombeväpning av historiska proportioner, med nya luftvärnssystem och en utökad organisation, för att möta det rådande säkerhetspolitiska läget i Östersjöregionen. I denna utveckling utgör den kontinuerligt anställda soldaten en viktig betydelse för att luftvärnsförbanden ska kunna lösa de tilldelade uppgifterna. För att djupare förstå och finna klarhet varför kontinuerligt anställda soldater väljer att sluta användes en kvalitativ forskningsmetod, genomsyrad av en induktiv ansats. Genom intervjuer med tidigare anställda soldater insamlades empiri som står på egen grund. Med en analysmetod inspirerad av Grounded Theory skapades det emotionella spänningsdiagrammet som förklarar varför individen väljer att sluta. I diskussionen kopplades forskningens resultat främst mot Herzbergs tvåfaktorsteori men resultatet sågs även ur ett generationsperspektiv. För den unga generation Z är personifiering genom personlig utveckling tillsammans med ledarskapet avgörande i soldaternas beslut att lämna sin anställning. Den omväxlande och utmanande verksamheten i Försvarsmakten bidrar till en stark känsla av gemenskap som i sin tur påverkar soldatens motivation att stanna kvar längre i sin anställning. Soldaten är även påverkad i sitt val att lämna eller stanna kvar vid förbandet av basala behov så som anställningsvillkor, lön och geografiskt läge. / At a time when the Swedish Armed Forces struggle with high soldier turnover, the Air Defense Regiment in Halmstad is facing a re-arming of historical proportions such as new air defense systems and an expanded organization to meet the current security policy situation in the Baltic Sea Region. In this development, the continuously employed soldier is an important factor in ensuring that the air defense units are able to fulfill their assigned tasks. In order to understand more deeply and find clarity why the continuously employed soldiers choose to leave, a qualitative research method, imbued with an inductive approach, was used. Through interviews with formerly employed soldiers empirics that stand on their own were collected. With an analysis method inspired by Grounded Theory, the emotional tension diagram was created that explains why the individual chooses to leave. In the discussion, the results of the research were mainly linked to Herzberg's two-factor theory, but the result was also seen from a generation perspective. For the young generation Z, personalization through personal development together with leadership is of major importance why the soldiers are determined to leave their employment. The varied and challenging activities of the Swedish Armed Forces contribute to a strong sense of community that affects the soldier's motivation to stay longer in one´s employment. The soldier is also influenced by basic needs in one´s choice to leave or stay at the unit such as employment conditions, salary and geographical location.

The traditional landings with large warships near the coastline have been replaced by means of vessels moving beyond the horizon from the coast where the landing will take place. The old landing crafts have been replaced by transport helicopters and close air support, a threat that the amphibious battalion lacks resources to meet. The Swedish Armed Forces faces a possible acquisition of MANPADS and therefore the main purpose with this study was to examine the systems: FIM-92 Stinger RMP, Mistral and RBS70 NG, in order to assess which one of them who had the greatest potential to be effective when used by the amphibious battalion in a coastal defense operation. The study was conducted as a multiple criteria decision analysis, based on the concept of military utility. The result indicated that the RBS70 NG was the system that best met the requirements and demonstrated the greatest potential to be military efficient, although Mistral with minor exceptions fulfilled the requirements. As the study was delimited to a theoretical study based on three specific scenarios, further studies are recommended with simulations, as well as field trials before the result can be given a higher validity. The result, however, already helps us to understand how MANPADS contributes with military utility in coastal defense operations. / De traditionella landstigningarna med stora fartyg uppträdandes kustnära har ersatts med metoder innebärandes att fartygen rör sig bortom horisonten från den kust där landsättningen/landstigningen ska ske. De gamla landstigningsbåtarna har i hög grad ersatts med helikoptrar som understödda av attackhelikoptrar och flygplan utgör den nya dimensionerande hotbilden. En hotbild som amfibiebataljonen saknar resurser för att möta. Då Försvarsmakten står inför en eventuell anskaffning av ett buret luftvärnssystem till amfibiebataljonen har denna undersöknings främsta syfte varit att bedöma vilket av systemen FIM-92 Stinger RMP, Mistral eller RBS70 NG som uppvisat störst potential att vara militärt effektivt när de nyttjas av en amfibiebataljon i kustförsvarsoperationer. Undersökningen genomfördes som en komparativ analys med multimålmetod och tre olika typfall som grund. Jämförelsen tog sin utgångspunkt kring teoribildningen om militär nytta och då mer specifikt militär effektivitet. Resultatet indikerade att RBS70 NG var det system som bäst mötte amfibiebataljonens krav och därmed uppvisade störst potential att vara militärt effektivt, även om Mistral med enstaka undantag också uppfyllde kraven till synes utan begränsningar. Då studien avgränsats till en teoretisk jämförelse i tre specifika typfall, rekommenderas fortsatta studier med såväl simuleringar som praktiska prov innan resultatet kan ges en högre validitet. Resultatet bidrar däremot redan nu till en förståelse för vad som ökar den militära effektivitetenvid genomförande av kustförsvarsoperationer.

International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / Since the Gulf War, there has been significant interest in Theater Missile Defense (TMD) resulting in funding growth from tens of millions of dollars at the time of the Gulf War to $1.7 Billion in 1994. The Ballistic Missile Defense Organization (BMDO) has developed a Theater Missile Defense test and evaluation program that will assess technological feasibility and the degree to which system functionality and performance meet technical and operational requirements. The complexity of the TMD program necessitates a comprehensive test program which includes flight testing, ground testing, and modeling and simulation. This article will provide and overview the requirements and capabilities needed to satisfy these requirements. The data processing, and telemetry communities will play a major role in providing the expertise to support the development of the nation’s future Theater Missile Defense capabilities.
