| 中文摘要 | 为研究目标雷达回波高逼真度模拟生成对雷达系统设计及雷达信息获取理论,通过物理光学的电磁计算模拟目标电磁特性,并结合系统参数和波形应用生成相应的雷达虚拟回波。为提高电大尺寸目标雷达回波模拟的计算效率,构建了一种基于通用图形计算卡(GPGPU)和中央处理单元(CPU)组成的异构并行硬件平台,结合并行软件编程技术实现高逼真度雷达回波快速生成,同时对并行优化策略,特别是多卡调度等并行化关键技术进行了设计,最终的并行软件平台回波生成效果表明了该平台在雷达系统设计和理论研究方面的潜力。; Obtaining an ideal simulated radar echo is of great importance in relative radar system design and radar information acquisition research. A method based on Physical Optics(PO) is proposed to calculate the electromagnetic scattering of target. The parameters of radar system and transmitted waveform are also considered during the calculation. In order to satisfy the requirement of rapid echo generation for electrically large target,a parallel platform which consists of General-Purpose computation on Graphics Processing Units(GPGPU) and Central Processing Unit(CPU) is built and the corresponding software is programmed. The whole system adopts some parallel optimization methods such as cluster scheduling. Numerical experiments demonstrate that the platform has a great potential for radar system design and research. |
