摘要
提出了一种基于FPGA的DBF发射天线数字波束形成网络的实现结构，利用分布式算法实现波束形成网络的乘累加结构，减少了硬件资源的费用以及代码开发的复杂度。根据波束赋形系数的对称性复用乘法器资源，进一步节省了FPGA逻辑资源的使用。16波束、61通道DBF发射天线的研制与实验结果表明，该结构适用于大规模高速阵列天线的开发。
Based on FPGA the implementation of digital beamforming net of DBF transmitting antenna is proposed. Distribution algorithm is used in order to reduce the spending of hardware resources and the complexity of programming. The reuse of the multipliers is achieved according to the symmetry of the beamforming coefficients, which makes it possible to further more reduce the logical resources of the FPGA. The development of 16-beam, 61-channel DBF transmitting antenna demonstrates that this implementation architecture is effective for high-speed and large scale transmit antenna array.
