US Patent:

6400308, Jun 4, 2002

Filed:

Oct 9, 1998

Appl. No.:

09/169679

Inventors:

David Allen Bell - Altadena CA
Jimmy Moon Kan Li - Monrovia CA
Roger Taur - Honolulu HI
Jess Delacueva - West Covina CA

Assignee:

Amerigon Inc. - Irwindale CA

International Classification:

G01S 1393

US Classification:

342 71, 342 70, 340901

Abstract:

A radar system is described for use in vehicular applications. The radar system is particularly suited to backup warning systems and lane-change warning systems. The radar minimizes many of the problems found in the prior art by providing programmable delays and programmable gain. The radar uses a range search algorithm to detect and sort targets at various ranges within the field of view of the radar. Each target range corresponds to a particular delay and gain setting. The radar searches for targets at the various ranges by running a target search algorithm. For each target range, the search algorithm causes the proper time delay and gain setting. Targets within the selected range are detected and catalogued. Speed of the targets is obtained through Doppler processing. A display is used to warn the driver of the vehicle of the presence of targets at the various ranges.
