Collision detection system and method of estimating miss distance employing curve fitting

摘要

A collision detection system (18) and method (40) of estimating a miss distance (M) of an object (16) are provided. The collision detection system (18) includes a sensor (12) for sensing an object (16) within a field of view (14) and measuring range (R) and range rate (R<&>) of the sensed object (16). The collision detection system (18) further includes a controller (20) for computing a mathematical square of the range (R) and computing a mathematical square of the product of range (R) and range rate (R<&>). The controller (20) estimates a miss distance (M) of the object (16) as a function of the computed squared range (R) and the squared product of range (R) and range rate (R<&>).
