Abstract

A vehicle radar system (3) and method including a first and second radar sensor arrangement (4a, 4b). Each radar sensor arrangement (4a, 4b) includes at least two transmitter antenna devices (10a1, 10a2) and at least two receiver antenna devices (13a1, 13a2, 13a3, 13a4), where each receiver antenna device (13a1, 13a2, 13a3, 13a4) has a corresponding boresight extension (46a, 46b) that is perpendicular to an antenna plane (57). Each receiver antenna device (13a1, 13a2, 13a3, 13a4) has a corresponding antenna radiation pattern (47a, 47b) that has a lower gain (48a, 48b) in its boresight extension (46a, 46b) than at a certain corresponding first maximum gain azimuth angle (φ1a, φ1b) where there is a first maximum gain (49a, 49b). Each radar sensor arrangement (4a, 4b) is mounted such that each first maximum gain (49a, 49b) is directed along a corresponding first maximum gain extension (51a, 51b), such that an overlap part (56) of the antenna radiation patterns (47a, 47b) is formed.
