Collision detection system and method of estimating target crossing location

Abstract

A collision detection system and method of estimating a crossing location (C) are provided. The system includes a first sensor (12A) for sensing an object (16) in a field of view (15) and sensing a first range (R1) defined as the distance between the object (16) and the first sensor (12A). The system also includes a second sensor (12B) for sensing the object (16) in the field of view and sensing a second range (R2) defined by the distance between the object (16) and the second sensor (12B). The system further includes a controller (20) for processing the first and second range measurements (R1 and R2) and estimating a crossing location (C) of the object (16) as a function of the first and second range measurements (R1 and R2). The crossing location (C) is estimated using range (R) and range rate (R&) in a W-plane (80) in one embodiment and using a time domain approach (120) in another embodiment.
