Abstract
A vehicle radar sensor unit () arranged to acquire a plurality of radar detections, and including an antenna arrangement (), a transmitter unit (), a receiver unit () and a processing unit (). The antenna arrangement () has at least two transmitter antennas () and at least two receiver antennas (), where two transmitter antennas () have a vertical spacing (h) between their respective phase centers () that exceeds half the free-space wavelength of the transmitted signal. The processing unit () is arranged to determine a first radial velocity of each radar detection by tracking the change of radial distance (r) to each radar detection for a plurality of radar cycles; determine a second radial velocity that best matches the first radial velocity; track a plurality of measured heights (z) as a function of radial distance (r); and to choose a measured height (z) among the tracked measured heights (z) that has a minimal change from radar cycle to radar cycle.
