    Sammanfattning : Within the military there is great need for reliable communication between vehicles. During the planning and construction of a military RIB, Rigid-hulled Inflatable Boat, it is important to design an efficient antenna system that does not deteriorate out of disorder. LÄS MER

  3. 7. 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. 8. Target Tracking using Maxwell’s Equations

    Uppsats för yrkesexamina på avancerad nivå, Reglerteknik

    Författare :Niklas Wahlström; [2010]
    Nyckelord :tracking; magnetic dipole; EKF; filter banks; observability;

    Sammanfattning : Starting from Maxwell’s equations, we derive a sensor model for three-axis magnetometerssuitable for localization and tracking applications. The model dependson the relative position between the sensor and the target, orientation of the targetand its magnetic signature. Both point targets and extended target modelsare provided. LÄS MER
