| 摘 要： | 针对宽带雷达目标回波在相参处理时间内存在越距离单元走动的问题,提出了一种基于过采样抽取子带处理的宽带雷达杂渡抑制与目标回波相参积累的方法.通过过采样离散傅立叶变换(DFT)调制滤波器组将宽带雷达回波分为若干子带,每个子带内目标回波不存在越距离单元走动,从而可以通过对相参回波序列的加权处理实现杂波抑制和目标回波的相参积累...

| Abstract: | To overcome the range walking of the wideband radar target returns during a coherent processing interval(CPI),the method of wideband radar clutter suppression and target return integration based on oversampled decimation subband processing is presented in this paper.The return is decomposed by oversampled discrete Fourier transform(DFT) modulation filter bank.In every subband,the range walking does not across range cells and weighting processing is implemented for multi coherent returns to suppress the clut... |
