摘　　要：传统的基于中央处理器(CPU)平台的相控阵雷达信号级仿真运行效率低,难以做到信号的实时处理,严重制约了信号级仿真的广泛应用。为了能实时实现相控阵雷达信号处理,利用图形处理器(GPU)拥有的众多计算单元,设计了一种基于GPU的相控阵雷达信号级并行仿真软件。新仿真在ArrayFire软件平台上开发,充分利用了GPU的硬件优势,降低了基于GPU的雷达仿真系统开发的难度。仿真结果表明,并行仿真使仿真速度有了较大提高,可以实时完成相控阵雷达系统运行的整个流程,具有十分光明的应用前景。The computational efficiency of the traditional coherent video simulation of phased array radar based on CPU is quite low.It’s very difficult to fulfill the real-time requirement of radar signal processing which seriously restricts the wide application of coherent video simulation.To make the best of GPU’s numerous calculation units,a radar signal processing parallel simulation based on GPU was designed in order to realize phased array radar signal processing in real time.The new simulation was developed on ArrayFire software platform,which makes full use of the hardware advantages of GPU and reduces the development difficulty of radar simulation system based on GPU.The simulation results show that the simulation speed is improved greatly and the whole process of radar system operation can be completed in real time.It has a very bright application prospect.
