US Patent 8248272 Detecting targets in roadway intersections

The present invention extends to methods, systems, and computer program products for detecting targets in roadway intersections. Transmit antennas transmit signals into a roadway intersection. Receive antennas receive corresponding signal reflections off objects in the roadway. The reflections correspond to two dimensional image data for the roadway intersection. The reflections are conditioned for compatibility with a processor. The processor processes the condition reflections into a two dimensional image of targets in the roadway intersection.
