1. 21. Conceptual Design of a Variable Air Inlet, JAS 39 Gripen

   Master-uppsats, Linköpings universitet/Maskinkonstruktion; Linköpings universitet/Tekniska fakulteten

   Författare :Malin Rosén; Andreas Boström; [2015]
   Nyckelord :;

   Sammanfattning : The JAS 39 Gripen currently has a static air inlet designed for cooling the engine bay. This inlet has been developed over the years and has consisted of several different solutions. In this master’s thesis an investigation of past and current designs has been conducted in order to develop new concepts with a variable solution. LÄS MER

3. 22. Multiple electromagnetic scattering by spheres using the T-matrix formulation

   Master-uppsats, Umeå universitet/Institutionen för fysik

   Författare :Marina Wallin; [2015]
   Nyckelord :T-matrix; Multiple scattering; RCS; FDTD; Electromagnetic scattering; Mie scattering;

   Sammanfattning : Low observable technology is used in order to prevent detection, or to delay detection. Radar cross section is an important parameter in aircraft survivability since it measures how detectable an object is with radar. To find the radar cross section Maxwell's equations are solved numerically in the time-domain using a finite difference scheme. LÄS MER

4. 23. Development of a Multidisciplinary Design Optimization Framework Applied on UAV Design

   Master-uppsats, Linköpings universitet/Maskinkonstruktion; Linköpings universitet/Tekniska fakulteten

   Författare :Athanasios Papageorgiou; [2015]
   Nyckelord :MDO; UAV; Optimization; Multidisciplinary; CAD; Aerodynamics; Sensor analysis; RCS; Mission simulation;

   Sammanfattning : The present thesis deals with the topic of Multidisciplinary Design Optimization (MDO) and in particular with the development of a framework for Unmanned Aerial Vehicle (UAV) design. The orientation of the research and the overall outlook of the case-study have been based on Saab’s proposal regarding the application of MDO in complex products and are in compliance with the guidelines of the Innovative Multidisciplinary Product Optimization (IMPOz) project initiative.

   Nyckelord :;

   Sammanfattning : The Master Thesis has been performed at ICA Sverige AB’s warehouse unit in Västerås. The unit is a central warehouse unit, distribution unit and distribution point. It delivers among others pantry and non-food products. LÄS MER

7. 25. Signal Processing for mmWave MIMO Radar

   Master-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

   Författare :Óscar Faus García; [2015]
   Nyckelord :radar; automotive; MIMO; CW; 79 GHz; short-range radars SRR ; millimeter wave; CFAR; simulations; phase modulation; algorithms; system gain;

   Sammanfattning : This thesis addresses the design study, implementation and analysis of signal processing algorithms for a 79 GHz millimeter-wave Phase Modulated Continuous Wave (PMCW) Multi Input Multi Output (MIMO) short range radar; performed in IMEC research institute (Leuven, Belgium). The radar system targets high resolution performance with low power consumption in order to integrate a full MIMO radar transceiver with digital processor and antennas in a compact package featuring a size of 1 cm2.
