Abstract
The present invention includes an anti-collision vehicular radar system which incorporates a microprocessor. The system provides a warning of a potential collision of the vehicle with other vehicles or objects in the path of the vehicle and automatic braking. More particularly, the present invention utilizes a pulsed radar system with overlapped antenna beams for off-axis object discrimination which determines the pattern of the change in relative velocity of the vehicle and the object which is detected by its radar to provide signals which are processed by a microprocessor and associated digital circuitry to determine whether the detected object is a potential obstruction which must be avoided by braking or maneuvering of the vehicle.
