摘　　要：分布交互式仿真试验系统的建立,带来了射频半实物仿真设备和数学仿真系统互连互通的需求;为解决异构数据的转换问题,设计了一套可接入射频半实物的试验数据转换硬件系统,通过系统中射频信号发生模块、中频数据回放设备、试验数据采集处理设备、数模转换模块、高速数字I/O模块和异构网络环境试验数据转换软件模块完成高频信号与数字仿真系统可用文件的相互转换;文章详细介绍了该系统各个模块的硬件架构和实现方法,并通过试验测试给出了测试结果,证明了通过该系统可以将射频半实物接入并实现其数据与数学仿真系统的相互利用。The application of RF hardware--in--the--loop in simulation demonstration system brings the need for the interactions between RF hardware--in--the--loop devices and mathematical simulation platform and other hardware--in--the--loop devices. To resolve the issue of the mutual usage of software and hardware simulation test data, a hardware system for the test data conversion for RF hardware --in--the--loop was designed. The conversion between the high frequency signal and digital simulation system can be accomplished by RF signal generator, data playback equipment, data acquisition and processing equipment, DA conversion module, high speed digital I/O mod- ule and software module of test data conversion in heterogeneous network environment. The hardware architecture and implementation of each module of the system are introduced in detail, and test results are presented, which proves the system can he used to achieve the inter action between the RF and the mathematical simulation system.
