Download or read book On Design of Coherent Multiple input multiple output Radars with Sparse Antenna Arrays written by Andreas Josef Kirschner and published by . This book was released on 2017-01-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The multiple-input multiple-output (MIMO) principle is traditionally well-known from communication applications. During the last years, this term has also found its way into radar system theory, signal design and signal processing, resulting in a large variety of experiments and publications. This thesis covers especially two topics: coherent MIMO radars and arrays with minimum redundancy. A theoretical approach to combine both fields is demonstrated. Furthermore, possible errors and deviations in hardware implementations are faced and encountered successfully in order to apply the retrieved principles on real radar sensors.
Download or read book Large Aperture Array Radar Systems for Automotive Applications written by Fabian Schwartau and published by Cuvillier Verlag. This book was released on 2021-10-18 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The radar, besides camera and Lidar systems, is a core sensor to enable autonomous driving. The relatively limited angular resolution is the major drawback of the radar. This thesis shows the development of a conceptual future radar system for automotive applications. The focus is on providing a large antenna aperture to achieve the required high angular resolution. Two genetic algorithms are developed to optimize the antenna array for a good side lobe level while providing high angular resolution. Two demonstrators are built to implement certain aspects of the proposed radar system and prove the general concept viable. The first demonstrator features a large aperture with a limited side lobe level and is using a modular approach. The modules are synchronized with a radio over fiber system. The second demonstrator uses the previously proposed antenna array, which is implemented with a synthetic aperture radar approach. The system’s capabilities in a real scenario are demonstrated, and the reconstruction of a high-resolution three-dimensional image from the captured data is shown. Das Radar stellt, neben Kamera- und Lidar-Systemen, einen zentralen Sensor für das autonome Fahren dar. Dabei ist die relativ geringe Winelauflösung der primäre Nachteil des Radars. Diese Arbeit zeigt die Entwicklung eines konzeptionellen zukünftigen Radarsystems für automobile Anwendungen. Der Schwerpunkt liegt auf der Umsetzung einer großen Antennenapertur, um die erforderliche hohe Winkelauflösung zu erreichen. Zwei evolutionäre Algorithmen werden vorgestellt, um das Antennen-Array auf einen guten Nebenkeulen-Pegel zu optimieren und gleichzeitig eine hohe Winkelauflösung zu erreichen. Zwei Demonstratoren werden gebaut, um bestimmte Aspekte des vorgeschlagenen Radarsystems zu implementieren und die Durchführbarkeit des allgemeinen Konzepts zu zeigen. Der erste Demonstrator weist eine große Apertur mit einem begrenzten Nebenkeulen-Niveau auf und verwendet einen modularen Ansatz. Die Module sind mit einem Radio-over-Fiber-System synchronisiert. Der zweite Demonstrator verwendet die zuvor entworfene Antennenanordnung, die mit einem Radar mit synthetischer Apertur realisiert wird. Die Fähigkeiten des Systems werden in einem realen Szenario demonstriert und die Rekonstruktion eines hochauflösenden dreidimensionalen Bildes aus den erfassten Daten gezeigt.

Download or read book Millimeter wave Circuits and Pulse Compression Radar Baseband analog Signal Processing Blocks in Silicon Processes written by Mehmet Parlak and published by . This book was released on 2012 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The power dissipation and cost of the next generation pulse radar beamforming systems needs to be reduced for the imaging and surveillance sensors. This research work aims at developing and innovating the next generation, mobile hand-held, high performance radar systems for outdoor surveillance applications, i.e. pedestrian detection sensor. Integrating the low cost millimeter-wave (mm-wave) imaging array platforms with advanced analog/baseband signal processing on silicon is proposed for reducing the power dissipation, area, and cost of the next generation radar modules and for the wide deployment of the sensors that are capable of detecting the vehicles and humans with a good range/angle resolution and maximum detection range at the same time. The system concepts of a bidirectional beamforming pulse compression radar system, the design and measurement results of the bidirectional mm-wave front-end circuits at the front-end and the design and measurement results of a baseband/analog signal processing sub-system and its blocks are presented, although the pulse compression radar is not fully demonstrated. Low noise figure, low power consumption, high linearity and high bandwidth in circuit level is maintained to provide the maximum detection distance, good range and angle resolution for the overall system level. The analog signal processing system is demonstrated in 90 nm CMOS process. The baseband circuitry is designed as a pulse compression radar system that exhibits the autocorrelation properties of the polyphase codes, maximizes the sensitivity and resolution of a pulse radar system and alleviates speed and resolution requirements of the ADC via an analog correlator while minimizing the power consumption. The baseband circuitry includes a Friis loss tracking VGA for high dynamic range, a correlator /integrator circuit, a comparator, and offset calibration circuits. The different lengths of radar codes are given as inputs to the baseband circuitry chip to find the time of flight. Next, novel silicon millimeter-wave frequency circuits are implemented to reduce the number of elements in a beamforming front-end, although not specifically designed for the radar system front-end. Bidirectional circuits are motivated by the requirements of scalable microwave and millimeter-wave phased array transceivers. The first bidirectional amplifier in silicon/silicon-germanium is reported to date - a W-band bidirectional cascaded constructive wave amplifier (BCCWA) in a 0.13[mu]m SiGe BiCMOS technology which operates as either an LNA or PA one at a time. The first phase shifter/variable gain amplifier at W-band in a 0.13 [mu]m SiGe BiCMOS technology is also reported to date. The circuit can operate both as a continuous variable gain amplifier and phase shifter one at a time. The first dual-channel distributed amplifier (DA) is reported to date. The DA is proposed for a highly linear multiple-input receiver front-end and can replace two LNAs at the same time. Next, millimeter-wave circuits in 45-nm CMOS SOI process are presented. The design and state-of-the-art measurement results of millimeter-wave (Q-band) balanced resistive ring mixer, LNA, and SPDT switch are demonstrated. The results indicate that 45-nm CMOS SOI demonstrates the lowest mixer conversion loss, lowest switch insertion loss, and lowest LNA noise figure compared to other CMOS processes.

This book was released on 2016 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: While MIMO radar's theoretical benefits have been well established in the literature, its practical limitations have not received great attention thus far. The effective use of MIMO radar techniques requires a diversity of signals, and to date almost all MIMO system demonstrations have made use of time-staggered transmission to satisfy this requirement. Doing so is reliable but can be prohibitively slow. Waveform-diverse systems have been proposed as an alternative in which multiple, independent waveforms are broadcast simultaneously over a common bandwidth and separated on receive using signal processing. Operating in this way is much faster than its time-diverse equivalent, but finding a set of suitable waveforms for this technique has proven to be a difficult problem. In light of this, many have questioned the practicality of MIMO radar imaging and whether or not its theoretical benefits may be extended to real systems.
