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 ? 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 ?, wherein the identified detections indicate a presence of a static object and/or a broadside vehicle.

Abstract: A system and method for generating alert signals in a detection system is described. The system compares data extracted from signals received via receive antenna beams with stored scenarios and determines whether to generate an alert signal based upon the results of the compare operation. The comparison of data extracted from received signals with stored scenarios can be accomplished by using one or more latches to process the extracted data from the received signals. In one embodiment, raw detections are pre-processed to generate so-called field of view (FOV) products. The FOV products are then provided to a tracker. In another embodiment, rather than pre-process the raw detections, the raw detections are instead provided directly to a tracker which processes the raw detections to provide products including, but not limited to, relative velocity and other parameters.

Abstract: A method of generating a target alert includes combining one or more object detection range values, an object relative velocity value, and a host vehicle velocity value to identify an alert. A system for generating a target alert includes a detection processor to provide one or more detection range values, a transceiver to receive a host vehicle velocity value, a relative velocity calculation processor to calculate a relative velocity value and an alert identification processor to combine the one or more detection range values, the relative velocity value, and the host vehicle velocity value to identify the alert.
