| 摘要: |
| 针对机载雷达任意形状共形阵列，在考虑阵元方向图及其安装指向的情况下，给出了阵元级统一杂波模型，在此基础上对共形阵的空域匹配滤波器进行了研究，给出了与常规平面阵不同的共形阵空域匹配滤波器形式。最后通过对几种典型机载共形阵天线的杂波仿真，分析了共形阵机载相控阵雷达的杂波分布规律，验证了模型的合理性，得出了有用结论。 |

| Abstract: |
| In view of the factors such as the element pattern and the element direction for an arbitrary airborne radar conformal array, the spatial snapshot and the subarraying are studied, and a general clutter model at the element level is introduced on the basis of the fact that the conformal array spatial matched filter, which is different from that of routine planar array, is provided. Finally, clutters and their distribution of several conformal arrays for airborne radar are simulated and analyzed respectively. The Results validates the feasibility of the clutter model. |
