Collision detection system and method of estimating miss distance
First Claim
Patent Images
1. A collision detection system comprising:
- an object detection sensor for sensing an object in a field of view and for measuring range to the object and range rate of the object; and
a controller for estimating a miss distance of the object as a function of the measured range and range rate, wherein the controller estimates the miss distance absent an azimuth angle measurement of the object.

Abstract
A collision detection system and method of estimating a miss distance are provided. The collision detection system includes a sensor for sensing an object in a field of view. The sensor measures range and range rate of the object. The collision detection system further includes a controller for estimating a miss distance as a function of the measured range and range rate, without requiring a measured azimuth angle measurement.
