Description: 在分析聚束合成孔径雷j盘(SAR)方位向时频关系的基础上，提出了一种新的全孔径分辨率SAR成像算法。
根据SAR在条带与聚束模式下回波信号之间的差别，利用现有成熟的条带SAR成像算法实现先对聚束SAR各方位向子
孔径成像，而后再将各方位子孔径带宽合成为全孔径带宽，以形成具有全孔径分辨率的SAR图像，极大降低了系统PRF
的要求。-In the analysis of spotlight synthetic aperture radar dish j (SAR) azimuth based on the time-frequency relationship, a new full-aperture resolution SAR imaging algorithm. According to SAR in strip and spotlight mode, the difference between the echo signal, the use of existing mature band SAR imaging algorithm first bit of the spotlight SAR the parties to the sub-aperture imaging, and then place then all the bandwidth synthetic aperture the bandwidth for the full aperture to form a full aperture resolution SAR images, greatly reducing the system PRF requirements.

Description: 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) Platform: |
