Digital proving ground, is modern shooting range, of high degree automation and integration, based on the digital information network covering the entire area of the proving ground, replied on highly visual trial and direction, connecting various proving grounds and each tache of the trial with computer-based digital communication subsystems and the information system platform, realizing the data identification, collection, transmission, processing, sharing and use of the information. This article based on the basic concepts, methods and principles of HLA, the function and characteristic of proving ground are analyzed, and according to the basic concept, method and principle of HLA, the system design of the distributed digital Proving ground missile penetration simulation system were carried on. On this foundation, system structure of the system was built, and the realization method of federation members classification and the design of FOM / SOM and members interface were introduced.
