本文将雷达偏振原理应用于合成孔径调频连续波雷达，给出了基于二维全偏振成像的结果。结果表明，合成孔径FM-CW雷达得到的极化目标反射系数是辛克莱散射矩阵的元素，尽管这些系数是由宽带信号导出的。利用散射矩阵优化方法，在实验室成功地对正交放置的线性目标集进行了二维偏振成像实验（包括Co-Pol最大值、最小值、跨度和相位成像）。该结果验证了s波段（8.2-9.2 GHz） FM-CW雷达偏振测量的有效性，为实现全偏振二维FM-CW成像雷达系统提供了一个示范
This paper applies the principle of radar polarimetry to a synthetic aperture frequency-modulated continuous wave (FM-CW) radar and presents results based on two-dimensional (2-D) full polarimetric imaging. It is shown that the polarimetric target reflection coefficients obtained by the synthetic aperture FM-CW radar are elements of a Sinclair scattering matrix, although the coefficients are derived from a wide band signal. Using the scattering matrix optimization procedure, a 2- D polarimetric imaging experiment (including Co-Pol maximum, minimum, span, and phase imaging) of an orthogonally placed linear target set was successfully carried out in the laboratory. This result demonstrates the validity of S-band (8.2-9.2 GHz) FM-CW radar polarimetry, and it presents a demonstration of a full polarimetric 2-D FM-CW imaging radar system
