摘要 研究合成孔径雷达(Synthetic Aperture Radar,SAR)双极化图像的H/α分解的特点及应用方法。在分析各种双极化组合模式下的H/α分解的计算方法及特点的基础上,针对HHVV组合方式下的双极化H/α分解给出替代参数,并与全极化模式下的H/α分解进行对比。理论分析和实验结果表明,该替代参数不但具有更加明确的物理意义,而且具有更高的计算效率。 This paper investigates the H /α decomposition and its characteristics under this imaging mode. The H /α decomposition under the dual polarization mode is discussed in this paper. Furthermore,the alternative parameters for the H / α decomposition corresponding to the HHVV dual polarization mode are proposed. Theoretical analyses and experimental results indicate that the alternative parameters have more accurate physical significance and less computation time.
