官方下载的MSTAR数据集。该实验数据采用美国国防高等研究计划署(DARPA)支持的MSTAR计划所公布的实测SAR地面静止目标数据，无论是在国内还是国际上，针对SAR图像目标识别的研究基本上是基于该数据集而展开的。采集该数据集的传感器为高分辨率的聚束式合成孔径雷达，该雷达的分辨率为0.3m×0.3m。工作在X波段，所用的极化方式为HH极化方式。(MSTAR data set downloaded from SDMS. The experimental data comes from MSTAR plans,the U.S. Defense Advanced Research Projects Agency (DARPA) SAR measured plans.either in domestic or international, researches on SAR image target recognition is basically carried out based on the data set. The sensor for this data set is a high resolution spotlight synthetic aperture radar (SAR) with a resolution of 0.3m * 0.3m. Working in X band, the polarization mode used is HH polarization mode)
