| 摘要: |
| 讨论了基于因式分解的穿墙雷达多输入多输出阵列配置方法，在此基础上提出了基于二维最小相位相干因子(2D Minimum Phase Coherence Factor，2D MPCF）加权的成像方法。2D MPCF综合了相位相干因子和距离向相位相干因子的优点，在方位向和距离向均有良好的栅瓣和旁瓣杂波抑制效果。仿真实验结果验证了所提成像方法不仅可以有效抑制杂波干扰，而且提高了成像结果分辨率。 |

| Abstract: |
| A polynomial factorization based multiple-input multiple-output(MIMO) array configuration method for through-the-wall radar is discussed.And then an imaging method based on two-dimensional minimum phase coherence factor(2D MPCF) weighting is proposed.The 2D MPCF factor combining the advantages of phase coherence factor(PCF) and range phase coherence factor(RPCF) has good grating lobe and sidelobe suppression effects in both the crossrange and downrange.Simulation results show that the proposed method can suppress the artifacts effectively and improve the resolution of imaging results. |
