  1. 1. A Travelling Wave Slot Array based on a Double-Layer Lens for 77 GHz Automotive Radar

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

    Author : Ashray Ugle; [2023]
    Keywords : Automotive radar; Double-layer lens; Gap waveguide technology; Waveguide slot; Antenna array; Lens-beamforming.; Bilradar; Dubbelskiktslins; Gap-vågledarteknik; Waveguide-kortplats; Antennuppsättning; Lens-beamforming.;

    Abstract : Automotive radars have gained considerable interest in recent years for applications of road safety for vulnerable road users. The use of multipleinput and multiple-output (MIMO) technology in automotive radar has helped in realising a virtual aperture greater than the physical aperture of the antenna which has reduced the size of the overall radar module.

  3. 2. Parking Map Generation and Tracking Using Radar : Adaptive Inverse Sensor Model

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Mohamed Mahmoud; [2020]
    Keywords : Vehicle; Parking; Radar; 2D Mapping; SLAM; Occupancy Grid Map; Binary Bayes Filter; Inverse Sensor Model; Noise Analysis;

    Abstract : Radar map generation using binary Bayes filter or what is commonly known as Inverse Sensor Model; which translates the sensor measurements into grid cells occupancy estimation, is a classical problem in different fields. In this work, the focus will be on development of Inverse Sensor Model for parking space using 77 GHz FMCW (Frequency Modulated Continuous Wave) automotive radar, that can handle different environment geometrical complexity in a parking space.

  4. 3. Micro-Shivering Detection : Detection of human micro-shivering using a 77 GHz radar

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Elyas Razzaghi; Arno Van Hoek; [2019]
    Keywords : micro-shivering; vibration; vital signs; mmwave radar; fmcw radar; chirp signal; snr; phase accuracy;

    Abstract : Radars have been under steady development to track, identify, image, and classify targets. Modern radar systems, with the help of embedded systems, have additional comprehensive signal processing capabilities. They can extract useful information from very noisy data, e.g. READ MORE

  5. 4. Transient Dynamics and Core Tunneling in Vertical Spin-Vortex Pairs

    University essay from KTH/Nanostrukturfysik

    Author : Milton Persson; [2019]
    Keywords : Spin-vortex; ultra fast vortex dynamics; milli-Kelvin temperatures; macroscopic quantum tunneling; Spinnvirvel; ultrasnabb virveldynamik; milli-Kelvin temperaturer; makroskopisk kvanttunnling;

    Abstract : Spin-vortices in vertically spaced pairs of thin elliptical Permalloy nanoparticles are investigated. The two vortex cores with parallel out-of-plane magnetization exhibit a strong monopole-like attraction through the spacer much thinner than the core length, thus forming a bound core-core pair.

  6. 5. Evaluation of Commercial Radar Sensors for Proximity Fuze Applications

    University essay from Umeå universitet/Institutionen för fysik

    Author : Sara Johansson; [2019]
    Keywords : ;

    Abstract : Radar sensors has been known for their usage in military applications but during the last decade commercial radar sensors have been implemented for usage in for example advanced driver-assistance system. One common implementation for advanced driver-assistance system is the adaptive cruise control technology implemented in vehicles to help it adapt the velocity based on the distance to a detected vehicle in front.
