  1. 16. Assessment of Aircraft Radar Cross-Section for Detection Analysis

    Författare :Björn Persson; Ulf Ringertz; Martin Norsell; Peter Bull; João Tasso de Figueiredo Borges de Sousa; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flyg- och rymdteknik; Aerospace Engineering; Försvarssystem;

    Sammanfattning : Hiding from and surprising an opponent are tactics that have been used in warfare throughout history. They were features that aircraft originally possessed when they were first used in military operations. However, development of military technology is an endless struggle between advances in technology and counter technology. LÄS MER

  3. 17. Human Engineering of Sensor Fusion Systems in Fighter Aircraft

    Författare :Peter Svenmarck; peter Wide; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A pressing concern in modern fighter aircraft cockpit design is how to present and reduce large amounts of data obtained from several sensor observations of the same object. Currently, sensor observations are presented individually as overlays or in different displays requiring the pilot to control each sensor and integrate observations. LÄS MER

  4. 18. Conjugate priors for Bayesian object tracking

    Författare :Yuxuan Xia; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bayesian estimation; object tracking; multi-object smoothing; backward simulation; automotive radar; extended object; conjugate prior; random finite sets; multi-object tracking; sets of trajectories.;

    Sammanfattning : Object tracking refers to the problem of using noisy sensor measurements to determine the location and characteristics of objects of interest in clutter. Nowadays, object tracking has found applications in numerous research venues as well as application areas, including air traffic control, maritime navigation, remote sensing, intelligent video surveillance, and more recently environmental perception, which is a key enabling technology in autonomous vehicles.

  5. 19. Snow contamination of cars: Collisions of ice particles with surfaces

    Författare :Tobias Eidevåg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ice adhesion; Snow adhesion; coefficient of restitution; particle impacts; premelting; radar blockage;

    Sammanfattning : Seasonal snow cover on roads causes car accidents that lead to human suffering and economic loss. Snow cover decreases visibility and road-tire friction. Advanced active safety systems have been developed to cope with sudden changes in driving conditions and have been engineered to act as quickly as possible. LÄS MER

  7. 20. Modelling and Retrieval of Forest Parameters from Synthetic Aperture Radar Data

    Författare :Maciej Soja; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Frequent, high-resolution mapping of national and global forest resourcesis needed for improved climate modelling, degradation and deforestation detection,natural disaster management, as well as commercial forestry. Synthetic aperture radar(SAR) is an active radio- or microwave-frequency imaging sensor, which can be optimisedto fit specific needs through the choice of the centre frequency. LÄS MER
