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.
