基于极化信息的两种距离对准新方法

该文尝试将极化信息应用于平动补偿中的距离对准,研究了两种基于极化信息的距离对准新方法:双通道平均相关法和瞬态极化WVD相关法。将这两种方法分别应用于实测数据进行了验证,结果表明,双通道平均相关法和基于瞬态WVD相关的距离对准方法能够明显提高距离对准精度,从而提升成像质量。

Two New Methods of Alignment of Range Profile Based on Polarization Information

Combination of polarization with high resolution is the development trend of advanced radar currently and in the future.In this paper,we try to apply polarization information to range alignment for translation movement compensation.Two range alignment methods based on polarization features are presented: Correlation of instantaneous polarization WV distribution and Correlation of double-channels averages.The efficiency of the two methods is demonstrated with the space objects measurement data respectively.The results show that both methods can improve the precision of range alignment.
