摘要
The present invention relates to a planar radar antenna (10) comprising an antenna array arrangement (11) with symmetric arrangement of receiving antenna elements (R1 - R5, R1' - R5`). In every half (HR, HL) of the antenna array arrangement, the receiving antenna elements (R1 - R5, R1' - R5') are non-linearly arranged, i.e. in such a way, that no more than two phase centers (15) are situated on a straight connecting line (CL), which connects any two of the phase centers (15) in any half (HL, HR). Preferentially, the phase centers (15) of the planar radar antenna are arranged in a W-shape or up-and-down sequence with consistent lateral spacing offset width (X1, X2) among at least three short-range antenna elements and inconsistent longitudinal spacing offsets (Y1, Y2, Y3).
