1. 1. Design of behavior classifying and tracking system with sonar

   Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

   Författare :Peter Westman; Mikael Andersson; [2008]
   Nyckelord :classification; association; active sonar; TBD; JPDA; HPDA; tracking; diver; particle filter; association; aktiv sonar; TBD; JPDA; HPDA; målföljning; dykare; partikelfilter; klassification;

   Sammanfattning : The domain below the surface in maritime security is hard to monitor with conventional methods, due to the often very noisy environment. In conventional methods the measurements are thresholded in order to distinguish potential targets. This is not always a feasible way of treating measurements. LÄS MER

3. 2. Modellbaserad ekoföljning i vätskefyllda tankar

   Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

   Författare :Christer Frövik; [2004]
   Nyckelord :Reglerteknik; Target tracking; radar; JPDA; modelling; FMCW; Reglerteknik;

   Sammanfattning : This thesis discusses model based tracking of radar echoes in tanks with liquid content. The errors in the measurements are not always random in these cases, and the interference that occurs when nearby echoes moves in relation to each other makes tracking difficult. LÄS MER

4. 3. Gruppmålföljning av markobjekt

   Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

   Författare :Johanna Solli; [2002]
   Nyckelord :Reglerteknik; målföljning; gruppmålföljning; markmålföljning; kalmanfilter; tracking.; Reglerteknik;

   Sammanfattning : This Masters Thesis considers tracking of ground targets. Since ground targets often are difficult to detect with sensors a track is easily lost in ground target tracking. The main question in this thesis is whether information on close targets and observations of them can be used to make the tracking more reliable. LÄS MER
