Abstract
A forward facing sensing system comprises a windshield electronics module disposed in the interior cabin of a vehicle at and behind the windshield. A radar sensor device is disposed within the windshield electronics module and a forward facing image sensor is disposed within the windshield electronics module, and with both disposed behind or adjacent to an upper region of the windshield. A control comprising an image processor analyzes images captured by the forward facing image sensor in order to, at least in part, detect an object present forward of the vehicle in its direction of forward travel. The radar sensor device may utilize beam aiming or beam selection or may utilize digital beam forming or digital beam steering or may comprise an array antenna or a phased array antenna or the forward facing image sensor may comprise a pixelated imaging array sensor. The radar sensor device comprises a silicon germanium radar sensor.
