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 ...
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 ...
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, ...
A 77-GHz cavity antenna array in PCB technology
Beitrag zu einer Konferenz
(Universität Ulm, 2016-01-11)
In this paper the design and the implementation of a cavity antenna array in PCB technology for automotive radar applications is presented. The array consists of four cavity antennas fed by a microstrip-line feeding network ...
Accuracy evaluation for antenna measurements at mm-wave frequencies
Beitrag zu einer Konferenz
(Universität Ulm, 2016)
Measurements of integrated antennas are often cumbersome and erroneous. Inaccuracies of the measurement setup, unknown material parameters, and metal parts in the immediate surrounding of the antenna under test (AUT) cause ...
Probe influence on integrated antenna measurements at frequencies above 100 GHz
Beitrag zu einer Konferenz
(Universität Ulm, 2016)
When measuring integrated antennas the signal has to be fed to the antennas with wafer probes. Wafer probes are commonly used to contact integrated circuits for on-chip measurements. As integrated radar and communication ...
Influence of the wafer chuck on integrated antenna measurements
Beitrag zu einer Konferenz
(Universität Ulm, 2016)
For meaningful pattern measurements of integrated antennas the devices, which are required during the measurement process, need to be optimized to influence the measurement results as little as possible. In this paper the ...
RCS measurements of a human hand for radar-based gesture recognition at E-band
Beitrag zu einer Konferenz
(Universität Ulm, 2016)
This paper presents monostatic radar cross section (RCS) measurements of a human hand in the frequency range from 60GHz to 90 GHz. These values are important parameters for system designs in the emerging field of radar-based ...
Digital true time delay for pulse correlation radars
Beitrag zu einer Konferenz
(Universität Ulm, 2016)
A novel concept for digital true time delay pulse correlation radars using digital programmable delay lines and monolithically integrated radar front-ends is investigated. The effects of quantization errors on side lobe ...
Adaptive clustering for contour estimation of vehicles for high-resolution radar
Beitrag zu einer Konferenz
(Universität Ulm, 2016-08-08)
Future automotive radars will be able to achieve much higher range and angular resolution compared to currently used radar sensors. This enables functionalities like vehicle contour estimation to be used in advanced driver ...
