Software Reuse Technology In Radar Countermeasures In The Simulation System For Distributed Data Processing Applications

Nowadays, the software reuse is popular in the software industry, because it can improve the speed of building, reduce the cost of development and make it easy for non-exporters to build the project. But, in the military simulation area, people find that it is difficult to use the software reuse because the figure about this area is complex and multiform. The problems of military simulation concentrate on two sides. First the traditional domain systems hardly support software reuse as a whole part; secondly the software engineers are not the domain specialists, so they can't build the domain model efficiently. These problems affect the expenses of product, the cycle of the development and the quality of product. So how to make the military simulation reusable has great value in the theory and application.This paper discusses these problems through two ways. One is that how to develop the reusable framework and COM component in the federate inner, which makes federate reusable in its inner model. The other is how to develop the federate based on the HLA and make the federate reusable in the whole federation system.This paper discusses how to develop federates in high-cohesion and low-coupling way, How to create a framework about distributing date processing and how to divide the domain development from the HLA federate development, which break through the limitation of reused just on the federate and code. Those have been availably approved and reused among the federation of radar reconnaissance equipment model based on HLA.This paper pay little emphases on introducing the technologies about the software reuse, but it describe about the process of analyze and design in detail. In this way the paper can support the system reuse on component and also on analyze and design.
