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 ...
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 ...
Enhancing angle estimation accuracy of ultra compact two-channel radar MMICs at 160 GHz using a biomimetic antenna array
Beitrag zu einer Konferenz
(Universität Ulm, 2019-09-20)
An ultra compact monostatic two-channel radar MMIC at 160 GHz with enhanced angle estimation accuracy is presented. The MMIC is built up of two transceivers as well as two chip integrated antennas. The small antenna aperture ...
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 ...
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 ...
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, ...
A Radar Measurement Setup with a Ground Truth System for Micro-Doppler Human Movements
Beitrag zu einer Konferenz
(Universität Ulm, 2019)
A Doppler-Tolerant Stepped-Carrier OFDM-Radar Scheme Based on All-Cell-Doppler-Correction
Beitrag zu einer Konferenz
(Universität Ulm, 2019)
Comparison of 2D and 3D compressed sensing for high-resolution TDM-MIMO radars
Beitrag zu einer Konferenz
(Universität Ulm, 2019)
In order to enhance the resolution of radar sensors, the sampling of the different measurement domains range, Doppler, and direction-of-arrival can be improved. This, for example, leads to the application of a sparse array ...
