Abstract: An airspace risk mitigation system includes a plurality of airspace input sources, an airspace data fusion and sensor coordination system, a communications link, and a risk mitigation support system. The airspace input sources includes a radar for generating radar data for an airspace, and an Automatic Dependent Surveillance-Broadcast (ADS-B) receiver for generating additional data for the airspace. The airspace data fusion and sensor coordination system is configured to receive airspace data from the plurality of airspace input sources, correlating airspace data with new or known objects in the airspace, fusing airspace data into a common airspace data set, and generating target and system status information. The risk mitigation support system is configured to calculate a risk associated with aircraft operation in the airspace as a function of the target and system status information.
