According to the function of distributed emulator, optical information processing and image multi-object tracking system, the following three aspects were emphasized in this dissertation. Firstly, a vast virtual terrain, ground radar models and canyons were created for the distributed emulator with modeling software Creator. The radars were driven to scan during emulating and the real time terrain code was sent to Radar module. Secondly, an optics channel simulating the optics camera of a virtual aircraft was implemented with simulating software Vega. The 2-D information got from the channel was translated and sent to multi-sensor information fusion system as an optics information source. Thirdly, the dissertation studied some motion estimation methods and analyzed the factors which influence the speed and the precision of the block matching algorithms. Then an improved block matching method was proposed for image multi-object tracking system and applied in the system combined with frame difference method.
