本发明公开了一种流水线结构的脉冲星非相干实时消色散系统及方法，预处理部分中，模数转换单元将输入的脉冲星基带信号转换为数字采样后的脉冲星信号，并输入给功率谱估计单元，功率谱估计单元得到脉冲星信号的功率谱，并传输至消色散处理部分；消色散处理部分中，输入缓冲输出功率谱信号给数据叠加单元，数据叠加单元将功率谱信号以流水线方式处理，与脉冲星数据缓冲单元中缓冲的信号叠加，得到时域功率信号，并传输给输出缓冲，输出缓冲缓冲时域功率信号；色散系数存储单元给出当前脉冲星数据需要写入脉冲星数据缓冲单元的位置，并传输给脉冲星数据缓冲单元。本发明解决了现有非相干消色散算法的信号处理速度、内存占用和分辨率损失问题。 The invention discloses a pulsar incoherent real-time achromatic system and method of a pipeline structure. In a preprocessing part, an analog-to-digital conversion unit converts an input pulsar baseband signal into a pulsar signal after digital sampling and inputs the pulsar signal to a power spectrum estimation unit; and a power spectrum estimation unit obtains a power spectrum of the pulsar signal, and transmits the power spectrum to the achromatic processing part. In the de-dispersion processing part, an input buffer outputs a power spectrum signal to a data superposition unit, the data superposition unit processes the power spectrum signal in an assembly line mode and superposes the power spectrum signal with a
