摘　　要：在研究了提高计算性能的并行技术的基础上,结合电磁环境的组成特征,构建了基于并行计算技术的雷达电磁环境仿真平台。经过测试验证,该平台能够模拟真实电磁环境中的雷达信号,实时生成到达雷达侦察设备天线口面的密集脉冲流数据,在20万脉冲/s的密度下平台的运行速度比采用串行设计时提高了3倍左右。A radar electromagnetic environment simulation platform is built based on the parallel technology that improves the computing performance and the composition characteristics of electromagnetic environment.It is verified that the platform can simulate radar signals in the real electromagnetic environment through the test,and generate dense pulse stream data reaching the antenna surface of the radar reconnaissance device in real-time.With the density of 0.2 million pps,the platform is running at a speed three times faster than that with serial computing.
