A multicopter-based focusing method for ground penetrating synthetic aperture radars
Beitrag zu einer Konferenz
(Universität Ulm, 2018)
A subsurface focusing method for multicopter-based mine detection using a ground penetrating synthetic aperture radar (GPSAR) is presented. In the first part of this paper, the challenges of a side-looking single-input ...
Done yet? A critical introspective of the cloud management toolbox
Beitrag zu einer Konferenz
(Universität Ulm, 2018-08-16)
With the rapid rise of the cloud computing paradigm, the manual maintenance and provisioning of the
technological layers behind it, both in their hardware and virtualized form, became cumbersome and error-
prone. This ...

Enhancing angle estimation for off-boresight targets using biomimetic antenna arrays
Beitrag zu einer Konferenz
(Universität Ulm, 2018-09-20)
Biomimetic Antenna Arrays (BMAAs) are able to enhance the angle estimation of miniaturized radar sensors by mimicking the hearing system of a fly. This technique has significant advantages over conventional approaches when ...
Characterization of a mm-Wave automotive radar with a Low-RCS MIMO antenna system
Beitrag zu einer Konferenz
(Universität Ulm, 2018-11-12)
Millimeter-wave (mm-wave) automotive radars are typically installed behind the car fascia. However, the placement behind the bumper can cause multiple reflections, which may lead to a wrong estimation of the direction of ...
Instantaneous actual motion estimation with a single high-resolution radar sensor
Beitrag zu einer Konferenz
(Universität Ulm, 2018-08-23)
Future high-resolution radars enable new functionalities in advanced driver assistance systems, relying on fast and reliable extraction of properties of vehicles on the road. A critical property for the prediction of ...
Towards a mm-wave planar biomimetic antenna array with enhanced phase sensitivity
Beitrag zu einer Konferenz
(Universität Ulm, 2016)
The design and measurements of a two-element biomimetic antenna array is presented with enhanced phase sensitivity at 20 GHz using planar structures only. The antenna array hereby mimics the hearing system of the parasitoid ...
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 ...
On hardware implementations of stepped-carrier OFDM radars
Beitrag zu einer Konferenz
(Universität Ulm, 2018-08-20)
Orthogonal frequency-division multiplexing (OFDM) is a promising candidate for future digital-centric radar
systems. One major limitation for practical implementations is the required sampling rate in the order of GHz, ...
Expanding the unambiguous velocity limitation of the stepped-carrier OFDM radar scheme
Beitrag zu einer Konferenz
(Universität Ulm, 2018-11-29)
The main limitation for the practical implementation of OFDM radars is the required high sampling rate of AD/DA converters. It can be solved by using a stepped-carrier OFDM scheme. Thereby, the same range and Doppler ...
