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.

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.
A collision detection system for detecting a miss distance to an object, said system comprising:
- an object detection sensor for sensing an object and measuring range to the object and range rate of the object;
- and
- a controller for estimating a miss angle of the object as a function of the measured range rate, said controller further estimating a miss distance of the object as a function of the measured range and the estimated miss angle.
A method of estimating a miss distance of an object, said method comprising the steps of:
- sensing the presence of an object with an object detection sensor;
- tracking the object;
- measuring range to the object;
- measuring range rate of the object;
- and
- estimating a miss distance to the object as a function of the measured range and range rate, wherein the estimation of the miss distance is computed absent an azimuth angle measurement of the object.
