| 摘要: |
| 本文首先应用TLS-ESPRIT算法提取光学区高分辨雷达目标散射中心位置信息, 并提出了“基于散射中心位置的相关匹配”目标识别算法, 而后, 证明了该算法相关匹配系数与所选择的基底无关以及算法的稳定性问题。最后, 给出了五种飞机缩比模型的实验结果。 |

| Abstract: |
| In this paper, first, the radar target scattering centers are extracted based on TLS-ESPRIT algorithm under high resolution radar in optical region, a new target recognition algorithm so-called“correlation match algorithm by scattering center situation information”is proposed. Then, the stability of this algorithm and the no-relation characteristics of correlation match coefficient and the selected base are demonstrated. Finally, the experiment results of five aircraft models are given. |
