Effort considerations of compressed sensing for automotive radar
Beitrag zu einer Konferenz
(Universität Ulm, 2019-01-21)
The application of iterative compressed sensing algorithms for automotive radar is often considered as too complex for real-time evaluation. In this paper, it is shown that the number of required iterations can be chosen ...
Compressed sensing based single snapshot DoA estimation for sparse MIMO radar arrays
Beitrag zu einer Konferenz
(Universität Ulm, 2019-04-25)
The angular resolution of a radar system can be enhanced with an increasing antenna aperture. Instead of using more antenna elements, the distances in the aperture can be increased with a sparse array. To mitigate the high ...
Optically transparent patch antennas at 77 GHz using meshed aluminum
Beitrag zu einer Konferenz
(Universität Ulm, 2019-04-25)
A process to realize optically transparent patch antennas with double-sided aluminum metalization of meshed structures on fused silica is presented in this paper. For cost-saving manufacturing, aluminum is used as metalization ...
Cooperative target detection in a network of single-channel radar sensors
Beitrag zu einer Konferenz
(Universität Ulm, 2019-04-25)
In automotive sensor networks the spatial distribution of the radar sensors allows to unveil additional information about the target objects. For example, the different angles to a target provide an increased robustness, ...
Clustering of closely adjacent extended objects in radar images using velocity profile analysis
Beitrag zu einer Konferenz
(Universität Ulm, 2019-06-03)
As high resolution automotive radars become more common, so does their usage for next-generation functionalities like advanced driver assistant systems and autonomous driving. This creates the need for robust clustering ...
Leakage phase noise mitigation for monostatic FMCW radar sensors using carrier transmission
Beitrag zu einer Konferenz
(Universität Ulm, 2019-08-06)
One common problem of frequency modulated
continuous wave radar is leakage from the transmitter to the
receiver. The leakage power is orders of magnitude larger than
the target return power and appears as a very strong ...
In-depth Analysis and Enhancements of RO-PUFs with a Partial Reconfiguration Framework on Xilinx Zynq-7000 SoC FPGAs
Beitrag zu einer Konferenz
(Universität Ulm, 2019-08-14)
Physical unclonable functions (PUFs) are excellent candidates to generate secret information on-chip without the need for secure storage. Ring-oscillator (RO) based PUFs have been receiving great attention over the years ...
Enhanced Arbiter PUFs using custom sized structures for reduced noise sensitivity
Beitrag zu einer Konferenz
(Universität Ulm, 2019-08-14)
This paper presents a simple yet effective way of improving delay based Physical Unclonable Functions by changing transistor gate sizes only. All utilized components of an Arbiter PUF were simulated in a 90nm CMOS process ...
Methoden zur Verbesserung von CMOS integrierten Arbiter-PUFs
Beitrag zu einer Konferenz
(Universität Ulm, 2019-08-16)
In diesem Beitrag wird eine Auswahl von Methoden zur Verbesserung integrierter CMOS PUFs vorgestellt. Am Beispiel der Arbiter-PUF zeigen wir, dass sowohl die PUF-definierenden Zufallsquellen erheblich optimiert werden ...
