Time Division Scattering Matrix Measurement of Moving Targets

摘要

摘要: 运动目标极化特性的测量是极化雷达探测与目标识别等领域非常关心的基础性问题。该文针对时分极化测量雷达，建立了动目标的瞬时极化测量模型。在深入分析目标极化回波的基础上，针对互易性目标，提出了一种基于交叉极化分量相位对齐的散射矩阵校准方法。研究结果表明在一定信噪比条件下，该测量和校准方法可以有效地消除因目标运动而导致的散射矩阵两列元素去相关。

Abstract: The topic of scattering matrix measurement of moving targets is very important in such fields as polarimetric radar and target recognition. In this paper, the problem of time division scattering matrix measurement of the reciprocal targets is discussed. A method of measuring and calibration based on aligning the phase of the cross-polarization of the scattering matrix is proposed. It is shown that the proposed measuring and calibration method can effectively eliminate the scattering matrix decorrelation caused by the target movement.
