Constantly evolving advanced driver assistance systems (ADAS) demand radar sensors with high angular resolution for object detection and classification. Improvement of angular resolution is conventionally achieved by increasing the number of transmit and receive antennas, which lead to higher cost, processing and thermal requirements. This has motivated the use of sparse multiple-input-multiple-output (MIMO) array topologies in automotive radars. However, the current topology synthesis methods rely on a quasi-random layout selection after an exhaustive search, which becomes suboptimal, and even infeasible for a large number of antennas. Besides, the electromagnetic (EM) effects, such as mutual coupling, are ignored in the system development phase, which causes performance degradation (degree of arrival (DoA) errors, high interference) and/or heavy calibration need.

To achieve high resolution and overall robust performance of angular estimation with sparse arrays, joint development of MIMO array topologies (sampling problem) and angular estimation algorithms (estimation problem) is required, while considering the physical effects (EM problem). The novel idea in DoAnt is to develop an EM-driven optimization framework for sparse radar sensor arrays integrated with DoA estimation. With its interdisciplinary nature, DoAnt aims to synthesize innovative sparse array topologies for automotive radar antennas at 77 GHz to improve performance, reliability and robustness of DoA estimation against EM non-idealities.

Faculty Electrical Engineering, Mathematics and Computer Science

The Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) brings together three scientific disciplines. Combined, they reinforce each other and are the driving force behind the technology we all use in our daily lives. Technology such as the electricity grid, which our faculty is helping to make completely sustainable and future-proof. At the same time, we are developing the chips and sensors of the future, whilst also setting the foundations for the software technologies to run on this new generation of equipment – which of course includes AI. Meanwhile we are pushing the limits of applied mathematics, for example mapping out disease processes using single cell data, and using mathematics to simulate gigantic ash plumes after a volcanic eruption. In other words: there is plenty of room at the faculty for ground-breaking research. We educate innovative engineers and have excellent labs and facilities that underline our strong international position. In total, more than 1000 employees and 4,000 students work and study in this innovative environment.
