Abstract:
1. A vehicle radar system, comprising; radar means for measuring a bearing of objects in front of a host vehicle and for measuring a distance of said objects from the host vehicle; radar Doppler filter means for measuring an apparent speed relative to the vehicle, for of said objects in front of the host vehicle; a host vehicle speed sensor; stationary object identifier means for identifying as stationary objects, those objects whose apparent speed, relative to the host vehicle is equal and opposite to sensed speed of a host vehicle; and computer means for detecting a misalignment of a radar boresight of said radar means relative to a direction of motion of the host vehicle and for applying an appropriate correction, as a function of changes of measured bearing with measured distance to stationary objects identified by said stationary object identifier means.
