The system you are asking about is called ASDE (and/or ASDE-X). Stands for Airport Surface Detection Equipment.
Not certain what system MDW currently uses; however, the system is designed to have specific coverage areas. Meaning the system knows to scan runways, taxiways, ramps, and areas determined necessary.
Chicago Midway is on track to get ASDE-X by 2011. This is system is has much more functionality compared to older systems; however, the system's goal is the same on either platform: spot potential collisions.
