US Patent:

6452534, Sep 17, 2002

Filed:

Apr 6, 2001

Appl. No.:

09/806964

Inventors:

Paul Kirk Zoratti - South Lyon MI
Jeffrey Schaefer - Chelmsford MA

Assignee:

Visteon Global Technologies, Inc. - Dearborn MI

International Classification:

G01S 1393

US Classification:

342 70, 342 71, 342 72, 701301, 340903, 340435, 340436

Abstract:

A radar field-of-view enhancement method particularly adapted for vehicle radar detection systems having a specified detection zone. In accordance with the invention, a pair of discrete radar beams are employed having differing arc widths. Return signals from the discrete beams are compared and related to the area of a desired detection zone. This approach increases the reliability of detection in the detection zone while minimizing false alarms and missed detection areas. The beams are alternately switched on using discrete sources or by implementing a discrete phase shifting element interposed between the sources.
