An improved sensor array for a mobile vehicle. The vehicle includes a centerline parallel to a vehicle velocity vector. The sensor array comprises a first sensor mounted to the mobile vehicle at a maximum lateral distance from the centerline near a first side of mobile vehicle and a second sensor mounted to the mobile vehicle at a maximum lateral distance from the centerline near a second side of the vehicle opposite the first side. The first sensor transmits a forward pointing first beam and the second sensor transmits a forward pointing second beam, both beams for detecting an object in the path of the vehicle. A plurality of first oblique beams are pointed to intersect the first beam and a plurality of second oblique beams are pointed to intersect the second beam. The oblique beams, in conjunction with the first and second beams form zones of overlapping beam coverage for better localization of objects in the path of the vehicle.
