Abstract
A method and apparatus for detecting static objects and broadside objects in a vehicular radar system is presented. Detection data within a field of view for a host vehicle is acquired. A histogram process is used to determine a presence of at least one of a static object and a broadside vehicle. The histogram process includes generating ratios of a relative velocity of an object (Vr) to host velocity (Vh) from acquired detection data and determining a number of detections which occur at an angle α corresponding to an intersection of two lines with a first line represented by Vr/Vh=0 and a region of a second line within the FOV along which Vr/Vh≠0. The detections are filtered to identify only those detection points at a first and second predetermined values of α, wherein the identified detections indicate a presence of a static object and/or a broadside vehicle.
