In order to realize the localization function replacement of remote communication system, a new idea is proposed based on reverse engineering method and embedded control technology. The localization of remote communication system is achieved through composing and function analyzing to the original one, using reverse engineering method and embedded control technology. On the special test bed, the performance compare test between the localized system and the original one is carried out. The tryout result indicates that the localized system can meet the application requirement of the imported weapon equipment, and it has been used in a factory and in the army to guarantee equipment maintenance and support. The reliance on the exporter is reduced, the maintenance cycle of the equipment is shortened effectively, and maintenance cost is saved, too.
