| 摘要: |
| 雷达目标宽带全极化测量在雷达成像、目标识别等领域有着重要应用，为此，基于正交频率分集思想，设计了一种用于宽带全极化瞬时测量的矢量信号波形；给出发射信号模型和回波信号模型，利用该波形的单个脉冲回波，可以获取测量带宽内多频点全极化数据，再经逆离散傅立叶变换后可以得到目标的全极化一维距离像；最后，用仿真数据和实测数据进行仿真实验，验证了该方法的有效性。 |

| Abstract: |
| Wideband full-polarization measurement for radar target is of important application in the research fields of radar imaging and target recognition. Based on orthogonal frequency division and full-polarization instantaneous measuring method, a new waveform vector was designed to get full-polarization information simultaneously under wideband condition. Firstly, the models of emitting and receiving signals were given, and full-polarization datum in frequency could be gathered, and then target full-polarization range profiles were obtained after IDFT. Finally, the validity of this measuring method was verified by simulation, using simulated datum and real measured datum. |
