摘　　要：提出了一种基于FPGA的宽带数字波束形成方法。采用全阵列和各子阵列协同处理的模式,在同一块FPGA平台上实现了全孔径处理模式和子孔径处理模式的动态切换。仿真实验和板上测试结果表明,该方法能够在不同工作模式下同时实现数字接收多波束和基于FFT的数字接收多波束,验证了本文方法的有效性。Awideband digital beamforming method is proposed based on FPGA.The dynamic switching between the full-aperture processing mode and the sub-aperture processing mode is realized on the same FPGA platform by using the co-processing mode of the full array and each subarray.The simulation results and on-board test results show that the proposed method can realize the digital receiving multi-beam and the FFT-based digital receiving multi-beam in different working modes,verifying the effectiveness of the method.
