| 摘 要： | 针对杂波谱移动非均匀和功率非均匀现象,提出了"频心"法非均匀检测器。该检测器利用杂波谱移动非均匀和功率非均匀环境下杂波散射中心频率和能量随距离变化这一特点进行非均匀样本选取。仿真结果证明这种非均匀检测器在杂波谱移动非均匀和功率非均匀环境下具有较好的非均匀检测性能。 |

| Abstract: | A new clutter non-homogeneity detector is proposed by using frequency center idea for clutter spectrum shifting and nonhomogeneity of clutter power enviroment. In clutter spectrum shifting and nonhomogeneity of clutter power enviroment the frequency and power of clutter spectral center chang with range which is used by this new approach to detect non-homogeneous samples.As a new non-homogeneity detector,the computer simulation results show good non-homogeneity detection performance can be obtained by this new detector in clutter spectrum shifting and nonhomogeneity of clutter power enviroment. |
| Keywords: | space-time adaptive processing(STAP) clutter suppression sample selection non-homogeneity detector(NHD) spectral center frequency method |
