Abstract

Current automotive radar sensors prove to be a weather robust and low-cost solution, but are suffering from low resolution and are not capable of classifying detected targets. However, for future applications like autonomous driving, such features are becoming ever increasingly important. On the basis of successful state-of-the-art applications, this work presents the first in-depth analysis and ground-breaking, novel results of polarimetric millimeter wave radars for automotive applications.

Abstract

The key importance of radar remote sensing for civil applications has been recognized for decades, and enormous scientific and technical developments have been carried out to further improve SAR sensors and SAR data processing.In recent years, SAR satellite constellations, consisting of two or more satellites, are becoming the “new normal” in SAR remote sensing. The present availability of SAR sensor constellations, such as Cosmo SkyMed, TerraSAR-X/TanDEM-X, and the new Copernicus sensors Sentinel-1A and 1B, supply a continuous stream of imagery with a unique short revisit cycle of only six days. Together with many more operational and planned SAR satellite systems, such as Geo-Fen 3 or NASA ISRO SAR (NISAR), this unprecedented amount of high-quality SAR data is suitable for a variety of applications, provided proper data processing methodology are applied.In "Advances in SAR: Sensors, Methodologies, and Applications" advancements in the field of hardware, software, and applications are presented, covering a wide range of topics.

Abstract

Die vorliegende Arbeit beschreibt eine neuartige Objektverfolgung durch Fusion von Radar- und Monokameradaten auf Merkmalsebene. In dieser Arbeit wird ein neues Assoziationsverfahren auf Basis der PDA-Methodik untersucht. Es wird ein Interacting Multiple Model Filter (IMMF) mit einer vollständigen, adaptiven Modellierung der Objektdynamik in Längs- und Querrichtung vorgestellt. Die Thematik Objektklassifikation sowie Gassenbreiteschätzung wird auch beleuchtet.

Abstract

The present work deals with a highly resolved radar with a synthetic aperture (synthetic aperture radar - SAR), which uses a beam steering to improve performance. The first part of this work deals with the influence of various effects occurring in the hardware of the High-Resolution Wide-Swath SAR (HRWS SAR) system. A special focus was set to single bit quantization in multi-channel receiver. The second part of this work describes SAR processors for Sliding Spotlight mode.

Abstract

This work describes the OFDM-based MIMO Radar-Communication System, intended for operation in a multiple-user network, especially the automotive sector in the vehicle-to vehicle/infrastructure network. The OFDM signals however are weak towards frequency offsets causing subcarrier misalignment and corrupts the radar estimation and the demodulation of the communication signal. A simple yet effective interference cancellation algorithm is detailed here with real time measurement verification.

Abstract

In der vorliegenden Arbeit wird ein neuartiges Systemkonzept für ein multifunktionales Radar- und Kommunikationssystem beschrieben, das es erlaubt, Radar-Sensorik und Funkkommunikation simultan und auf Basis einer gemeinsamen Sendesignalform zu realisieren. Als Sendesignalform kommen hierbei klassische OFDM-Signale zum Einsatz, die die technologische Basis vieler aktueller Funkstandards bilden. Beispielhaft wird eine Anwendung des Verfahrens im Automobilbereich betrachtet.

Abstract

In dieser Arbeit werden dual-orthogonal, linear polarisierte Antennen für die UWB-Technik konzipiert. Das Prinzip zur Realisierung der Strahler wird vorgestellt, theoretisch und simulativ untersucht, sowie messtechnisch verifiziert. Danach werden Konzepte zur Miniaturisierung der Strahler dargelegt, die anschließend zum Aufbau von Antennengruppen verwendet werden. Die Vorteile der entwickelten Antennen werden praktisch anhand des bildgebenden Radars und des Monopuls-Radars gezeigt.

Abstract

This thesis describes methods and techniques for realizing a fully integrated radar sensor in the frequency range above 100 GHz. The wavelength in the milimeter range leads to an antenna size in the range of a semiconductor die. This allows integrating antennas and a system-on-chip radar IC in a common chip package. Hence a fully integrated radio frequency system results within the chip package. This leads to a miniaturized, low-cost radar sensor for variuos applications.
