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.

Gegenwärtige Fortschritte in der Entwicklung autonomer Fahr- und Fahrerassistenzsysteme (FAS) führten zu einer Revolution in der Automobilindustrie. Wachsende Sorgen über Fehlalarmraten von Automobil-Radarsensor leiteten eine intensivere Forschung auf diesem Gebiet ein. Um Automobil-Anzeigesysteme im Allgemeinen und Fahrzeug-Radarsensoren im Besonderen zuverlässiger zu machen, ist eine akkurate Umgebungsbeschreibung entscheidend. Polarimetrische Radarsysteme bieten eine bessere Lösung zur genauen Beschreibung der Automobilumgebung und der Verkehrsszene. Abgesehen von der Bereitstellung genauer Einschätzungen des Bereichs und der relativen Geschwindigkeit kann durch die Verwendung polarimetrischer Radare in Fahrzeugen auch die Vielfalt der Objekte in der Verkehrsszene wie Fahrzeuge, Fußgänger, Straßenoberflächen und Hindernisse erkannt werden, wenn sie sich an derselben Position befinden. In der vorliegenden Arbeit wurde ein 77-GHz-Mehrantennen Radar (Multiple Input Multiple Output, MIMO-Radar) in Hauptstrahlrichtung kalibriert. Darüber hinaus wurden polarimetrische Zerlegungsalgorithmen auf verschiedene gemessene kanonischen Ziele angewendet und die Ergebnisse analysiert. Basierend auf den Ergebnissen der Algorithmen wurde beobachtet, dass die gemessenen Objekte je nach Typ wie punktartige oder verteilte Zielobjekte, Geometrie oder Orientierung, klassifiziert werden können.

The recent launches of three fully polarimetric synthetic aperture radar (PolSAR) satellites have shown that polarimetric radar imaging can provide abundant data on the Earth’s environment, such as biomass and forest height estimation, snow cover mapping, glacier monitoring, and damage assessment. Written by two of the most recognized leaders in this field, Polarimetric Radar Imaging: From Basics to Applications presents polarimetric radar imaging and processing techniques and shows how to develop remote sensing applications using PolSAR imaging radar. The book provides a substantial and balanced introduction to the basic theory and advanced concepts of polarimetric scattering mechanisms, speckle statistics and speckle filtering, polarimetric information analysis and extraction techniques, and applications typical to radar polarimetric remote sensing. It explains the importance of wave polarization theory and the speckle phenomenon in the information retrieval problem of microwave imaging and inverse scattering. The authors demonstrate how to devise intelligent information extraction algorithms for remote sensing applications. They also describe more advanced polarimetric analysis techniques for polarimetric target decompositions, polarization orientation effects, polarimetric scattering modeling, speckle filtering, terrain and forest classification, manmade target analysis, and PolSAR interferometry. With sample PolSAR data sets and software available for download, this self-contained, hands-on book encourages you to analyze space-borne and airborne PolSAR and polarimetric interferometric SAR (Pol-InSAR) data and then develop applications using this data.

This 2001 book provides a detailed introduction to the principles of Doppler and polarimetric radar, focusing in particular on their use in the analysis of weather systems. The design features and operation of practical radar systems are highlighted throughout the book in order to illustrate important theoretical foundations. The authors begin by discussing background topics such as electromagnetic scattering, polarization, and wave propagation. They then deal in detail with the engineering aspects of pulsed Doppler polarimetric radar, including the relevant signal theory, spectral estimation techniques, and noise considerations. They close by examining a range of key applications in meteorology and remote sensing. The book will be of great use to graduate students of electrical engineering and atmospheric science as well as to practitioners involved in the applications of polarimetric radar systems.
