摘要
提出了以吞吐率最大为准则利用频域分段算法进行FIR滤波的方法。推导了雷达信号处理中正交插值和脉冲压缩处理的频域算法,针对长信号序列的频域滤波处理,研究了分段滤波方法,得出了最佳分段长度。并将正交插值和脉冲压缩处理在频域合并起来,进一步降低了运算量。
The method of FIR filtering that takes maximum real-time signal processing throughput as principle and using frequency domain segmental algorithm is presented. The frequency domain algorithm of quadrature interpolation and pulse compression in radar signal processing is derived. Segmental filtering method is studied in view of frequency domain filtering processing of long signal sequence so that optimum segment length is achieved; and the total operand is further reduced by combining processes of quadrature interpolation and pulse compression in frequency domain.
