Abstract: A system is provided for real-time, in-flight simulation of a target. A sensor system may generate a live stream of an environment of an aircraft during a flight thereof, the live stream having associated metadata with structured information indicating a real-time position of the aircraft within the environment. A target generator may generate a target image from a source of information from which a plurality of different target images may be generable. The target generator may also generate a synthetic scene of the environment including the target image. A superimposition engine may then superimpose the synthetic scene onto the live stream such that the target image is spatially and temporally correlated with the real-time position of the aircraft within the environment. The live stream with superimposed synthetic scene may be output for presentation on a display of the aircraft during the flight.
