Abstract: In order to meet the requirements of the joint test of radar weapons and equipment, the development process of foreign theory and architecture of the joint test of radar weapons and equipment were illustrated in detail. With that, the research status of domestic theory and architecture of the joint test of radar weapons and equipment were analyzed. By comparing TENA and JoSim, development of middleware, object model and resource database of the domestic joint test platform were summarized. Finally, the future development trend of the joint test of radar weapons and equipment was prospected.
