摘　　要：针对目前雷达系统对数字波束形成的要求越来越高,传统FPGA实现的方法已无法满足系统要求的问题,本文提出了一种基于VxWorks+FPGA平台的雷达数字波束形成方法,通过计算机求得阵元级波束系数,再运用FPGA的高速率乘法器进行阵面波束合成,大大提高了DBF的实时性、可靠性、可拓展性。最后,运用实际算例仿真验证了该方法的有效性。Radar systems have increasingly higher requirements on digital beam-forming technology,so that the traditional FPGA implementation method cannot meet the system requirements.In this paper,a radar digital beam-forming method based on VxWorks and FPGA is proposed.With this method,the element level beam coefficients are determined through a computer,and then the high speed multiplier of FPGA is used for the array beam synthesis,which significantly improves the real-time performance,reliability,and scalability.Finally,an example is given to verify the effectiveness of the proposed method.
