The angle estimation capabilities of radar sensors are strictly linked to the antenna spacing between the array elements. A larger array aperture corresponds to a smaller beam width or in terms of the angle estimation a higher phase sensitivity. So-c

To enhance the capabilities of high-resolution imaging or beamforming, the trend goes towards arrays with high-channel count and large aperture sizes. The operation at increasing mm-wave frequencies exacerbates the consequences of manufacturing toler

Future driver assistance and autonomous driving systems require high-resolution 4D imaging radars that provide detailed and robust information about the vehicle's surroundings, even in poor weather or lighting conditions. In this work, a novel high-r

For multistatic radar networks in the upper mm-wave range with a large spacing between its radar sensor nodes, a coherent signal distribution is very complex and thus very costly. Hence, it is desirable to generate the mm-wave signals individually fo

In the upper millimeter wave range above 100 GHz, the effect of array imperfections like manufacturing uncertainties and mutual antenna coupling increases, which leads to deviations from the nominal antenna positions and angle-dependent errors in dir

The estimation of the direction-of-arrival in a coherent multi-channel radar system requires the distribution of the high-frequency local oscillator signal to all hardware channels. Various system concepts with distribution network or feedthrough top

Biomimetic antenna arrays inspired by the fly Ormia ochracea showed a promising improvement of the angle estimation capabilities of radar sensors. So far, there is usually a loss of output power associated with this improvement decreasing the detecta
