Multi-source fusion operations in subjective logic
Beitrag zu einer Konferenz
(Universität Ulm, 2018-06-10)
The purpose of multi-source fusion is to combine information from more than two evidence sources, or subjective opinions from multiple actors.
For subjective logic, a number of different fusion operators have been proposed, ...
Data rate reduction for chirp-sequence based automotive radars using compressed sensing
Beitrag zu einer Konferenz
(Universität Ulm, 2018)
For autonomous driving high-resolution radar sensors are key components, which have the drawback
of high data rates. In order to reduce the amount of sampled data, random samples can be omitted
and afterwards ...
Range migration compensation for chirp-sequence based radar
Beitrag zu einer Konferenz
(Universität Ulm, 2016-05-02)
To improve the range and Doppler resolution the bandwidth and the observation time need to be
increased. This leads to a range migration effect and thus to a declining separability of targets.
This paper compares ...
Automotive radar interference mitigation by reconstruction and cancellation of interference component
Beitrag zu einer Konferenz
(Universität Ulm, 2015)
Automotive radar interference is an issue arising
with the increasing amount of radar systems in automotive
scenarios. Interference can influence the functionality of a
radar system, e.g. decrease its detection capability. ...
Polarimetric RCS analysis of traffic objects
Beitrag zu einer Konferenz
(Universität Ulm, 2018-01-18)
Polarimetry capable antennae, with a unique design feature, are presented which were used to perform radar cross section (RCS) measurements of traffic signs at 77 GHz. An analysis of the results in the light of near field ...
SAR imaging in an automotive scenario
Beitrag zu einer Konferenz
(Universität Ulm, 2016-01-11)
In this paper a 77 GHz patch array radar is used in combination with the line processing and range Doppler algorithms to produce synthetic aperture radar (SAR) images of automotive scenarios. Measurements are made using a ...
Optimization of a MIMO radar antenna system for automotive applications
Beitrag zu einer Konferenz
(Universität Ulm, 2017-05-18)
Multiple-Input Multiple-Output (MIMO) radars can improve the angular resolution of automotive radar sensors. In MIMO radars, a critical design parameter is finding the optimal placement of the transmitting and receiving ...
Design and experimental characterization of a surface with low radar cross-section at millimeter-wave frequencies
Beitrag zu einer Konferenz
(Universität Ulm, 2017-01-19)
The investigation of low radar cross-section (RCS) structures is of great practical interest for the car integration of radar systems. This paper presents for the first time the study of a low-RCS surface at millimeter ...
A dielectric lens antenna fed by a flexible dielectric waveguide at 160 GHz
Beitrag zu einer Konferenz
(Universität Ulm, 2017-05-18)
Flexible antennas in radar applications enable the
user to go around obstacles or detect targets at hidden places.
In this paper, two elliptical lenses of different size made of
high density polyethylene and stacked on ...
Investigation on a 77-GHz broadside Vivaldi antenna
Beitrag zu einer Konferenz
(Universität Ulm, 2016-06-02)
Vivaldi antennas are excellent radiating elements that provide high gain and wide bandwidth. However, due to their end-fire radiation pattern they are not suited for the integration in printed circuit board (PCB) technology, ...
