Abstract: A radar antenna arrangement includes a plurality of transmitting elements and with a plurality of receiving elements. The transmitting elements are arranged in a transmitting arrangement and the receiving elements are arranged in a receiving arrangement, in each case in fields of a regularly hexagonally parqueted surface. An associated virtual antenna arrangement of virtual antenna elements results from the geometrical convolution of the transmitting arrangement with the receiving arrangement. High angular resolution and good alignability with good directional independence can be achieved by arranging the receiving elements in the receiving arrangement and the transmitting elements in the transmitting arrangement so that the virtual antenna elements in the virtual antenna arrangement are arranged without overlap.

Abstract: A method for determining the fill level of a medium involves continuous wave radar measurement and a corresponding fill level measuring device. A coded transmit signal is emitted by a transmitter, reflected at the medium, and received by a receiver as a reflection signal. The reflection signal and a signal derived from the transmit signal are subjected to a correlation analysis, and a correlation outcome results. A control and evaluation unit determines the time offset of the correlated signals with the correlation outcome, and uses it to determine the fill level of the medium. The reflection signal and the derived signal are mixed with the analog mixer into a mixer output signal that is sampled and quantized to a digital mixer output signal. The correlator has a digital integrator with which a sequence of digital mixer output signals is digitally integrated into the correlation outcome.
