摘要
针对现代相控阵雷达信号处理的要求,提出了一种高速、可变长、混合基8/4/2块浮点的FFT算法,给出了一种基于Altera公司Stratix系列FPGA芯片实现频域脉压的设计方案。结果表明,此模块既有专用ASIC的快速性,又有DSP器件的灵活性。
In accordance with the requirement of modern phased array radar signal process,a new method is proposed to design configurable,mixed-radix8/4/2 and block-floating-point high-speed FFT processor,the designing schedule of pulse compression in frequency domain based on Altera Stratix FPGA is given.,experiments show that the module has both high-speed performance of the ASIC circuit and flexibility of DSP component,the module is applied successfully in engineer domain.
