2. 1. Advanced Dual Circularly Polarized Antenna for Automotive Radar Systems

   Author : Zhaorui Zang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radar; Antenna; polarimetric radar.; automotive; gap waveguide; dual circular polarization; low-profile;

   Abstract : Advanced driver assistance systems (ADAS) promise reliable support for collision avoidance and cruise control. The demand for precise target classification and road surface sensing requires a sensor revolution. In this regard, the automotive radar system is highly expected to collect as much information as possible. READ MORE

4. 2. Estimation Problems in Array Signal Processing, System Identification, and Radar Imagery

   Author : Richard Abrahamsson; Peter Stoica; A. Lee Swindlehurst; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parameter Estimation; Array Signal Processing; STAP; SAR; Ground Penetrating Radar; System Identification; Bilinear Models; Covariance Matrix Estimation; Signal processing; Signalbehandling; Signalbehandling; Signal Processing;

   Abstract : This thesis is concerned with parameter estimation, signal processing, and applications. In the first part, imaging using radar is considered. More specifically, two methods are presented for estimation and removal of ground-surface reflections in ground penetrating radar which otherwise hinder reliable detection of shallowly buried landmines.

5. 3. Efficient parallell architectures for future radar signal processing

   Author : Anders Åhlander; John L. Gustafson; Högskolan i Halmstad; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer architecture; radar signal processing; space-time adaptive processing; synthetic aperture radar; parallel processing; engineering efficiency; Computer science; Datalogi;

   Abstract : The processing demands on future embedded radar signal processors may stretch to several trillions of floating-point operations per second (TFLOPS). This is an increase of two to three orders of magnitude realtive to the requirements of today. Still, the tight size and power constraints are unchanged. READ MORE

6. 4. Resource Allocation in Airborne Surveillance Radar

   Author : Johannes Wintenby; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radar resource management; radar control; sensor management; surveillance radar; electronically scanned antenna; adaptive tracking; resource allocation;

   Abstract : Radars equipped with an Electronically Scanned Antenna (ESA) have the potential of directing the electromagnetic radar beam without mechanically adjusting the antenna. Furthermore, the beam can be redirected instantaneously towards any location in space. READ MORE

7. 5. Human Detection and Tracking with UWB radar

   Author : Melika Hozhabri; Maria Lindén; Nikola Petrovic; Martin Ekström; Robin Augustine; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UWB radar; signal processing; human detection; elektronik; Electronics;

   Abstract : As robots and automated machineries are increasingly replacing the manual operations, protecting humans who are working in collaboration with these machines is becoming an increasingly important task. Technologies such as cameras, infra-red and seismic sensors as well as radar systems are used for presence detection and localization of human beings. READ MORE
