  1. 6. ISAR Imaging Enhancement Without High-Resolution Ground Truth

    University essay from Linköpings universitet/Datorseende

    Author : Moltas Enåkander; [2023]
    Keywords : SAR; SAR Imaging; ISAR; ISAR Imaging; Machine learning; Convolutional neural network; CNN; neural network; Super resolution; Unsupervised learning;

    Abstract : In synthetic aperture radar (SAR) and inverse synthetic aperture radar (ISAR), an imaging radar emits electromagnetic waves of varying frequencies towards a target and the backscattered waves are collected. By either moving the radar antenna or rotating the target and combining the collected waves, a much longer synthetic aperture can be created. READ MORE

  3. 7. Initial Orbit Determination of Resident Space Objects From A Passive Optical Imaging System: : Application to Space Situational Awareness

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Jessica McKenna; [2023]
    Keywords : Space Situational Awareness; Space Science; Angles-Only Initial Orbit Determination;

    Abstract : The probability of satellite collisions and disintegrations cluttering the near-Earth orbital environmentis ever-growing. This is especially true for the congested Low Earth Orbit (LEO) regime; once a critical density of objects is reached, a collisional cascading is projected to generate runaway growth of theorbital population.

  4. 8. Intelligent Headlamp Levelling : Thesis work at Scania CV AB

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Peder Palm Lamerstedt; Christopher Fingalsson; [2023]
    Keywords : Headlamp Levelling; Automatic Levelling; Automotive headlamp Levelling;

    Abstract : Illumination of the road environment plays an important role for the night-time vision of the driver and in general road safety. The purpose of this thesis is to develop a proof of concept that can measure the vertical angular displacement of a truck headlamp relative to the road. READ MORE

  5. 9. Server-side factor graph optimization for on-manifold pre-integration in IoT sensors

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Samuel Gradén; [2023]
    Keywords : Edge computing; IoT; optimization; tracking; drone;

    Abstract : State and specifically location estimation is a core concept in automation and is a well-researched field. One such estimation technique is Moving Horizon Estimation (MHE). In this thesis, the MHE variant single-shooting estimation will estimate the location and velocity of a moving object. READ MORE

  6. 10. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)
