摘　　要：针对雷达电子战信号级仿真系统运行效率低的问题,提出了一种新的系统架构设计思路。能通过共享内存的数据交互方式,解决网络数据通信传输耗时问题,能利用支持并行计算的多CPU服务器架构,通过引入并行计算技术,解决信号级模型运算耗时大的问题,能通过将仿真显控与模型运算分离,解决仿真界面显示耗时问题,并据此构建了仿真原型系统,在商用PC机硬件环境上进行了仿真运算速度的初步测试。测试结果表明该系统架构对仿真运行效率有较大的提升。Aiming at the problem of low efficiency of radar EW signal level simulation system,a new system architecture design idea is presented,which can solve the time-consuming problem of network data communication transmission through shared memory data interaction mode. The multi-CPU server architecture supporting parallel computing is utilized,and the time-consuming problem of signal level model operation is solved by introducing parallel computing technology. By separating simulation display and control from model operation,the time-consuming problem of simulation interface display can be solved. Based on this, a simulation prototype system is constructed. The preliminary test of simulation operation speed in the hardware environment of commercial PC is carried out. The test results show that the system architecture can greatly improve the efficiency of simulation operation.
