摘    要:针对SAR目标图像对于目标姿态的高度敏感性的问题,基于相关匹配算法详细研究了目标图像随着方位角变化的统计规律。利用MSTAR实测目标数据,在进行了图像的分割和象素幅值的归一化之后,每一幅测试图像都和所有训练图像序列进行相关匹配,并产生匹配值,进而得到相关匹配图。实验发现,相关匹配图随着方位角的变化近似于正弦曲线,整个训练序列表明了一个测试目标和它的同样方位的训练图像以及180度方位翻转的训练图像存在着局部最大的相关性。

关 键 词:合成孔径雷达  目标  相关匹配算法

Abstract:For the problem of the high sensitivity that the image of SAR target to target's pose,we analyzed the statistical trend in azimuth based on correlation algorithm.Utilizing MSTAR measured target data,each test image was correlated with all the training images to generate correlation and classification statistics and correlation plots.By experiments,the correlation plots varied approximately sinusoidally with aspect,and all the training sets showed that a target was highly correlated with both the correct aspect angle and the correct angle rotated 180 deg,and this two correlation scores corresponded to the two local amplitudes of the correlation plot.
Keywords:SAR  Target  Correlation algorithm
