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)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.

2. Image Reconstruction Techniques using Kaiser Window in 2D CT Imaging
University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Abstract : The traditional Computed Tomography (CT) is based on the Radon Transform and its inversion. The Radon transform uses parallel beam geometry and its inversion is based on the Fourier slice theorem. READ MORE

3. Rotation Invariant Registration of 2D Aerial Images Using Local Phase Correlation
University essay from Institutionen för informationsteknologiAbstract : Aerial image registration requires a high degree of precision. In order to improve the accuracy of feature-based registration, this project proposes a novel Log-Polar Transform (LPT) based image registration. Instead of using the whole image in the conventional method, feature points are used in this project, which reduces the computational time. READ MORE

4. On Generating Complex Numbers for FFT and NCO Using the CORDIC Algorithm
University essay from Institutionen för systemteknikAbstract : This report has been compiled to document the thesis work carried out by Anton Andersson for Coresonic AB. The task was to develop an accelerator that could generate complex numbers suitable for fast fourier transforms (FFT) and tuning the phase of complex signals (NCO). Of many ways to achieve this, the CORDIC algorithm was chosen. READ MORE
