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.)

现,对细化指纹图像的断裂有很好的修复效果。(The broken ridge fingerprint image processing equipment, image enhancement and other causes will generate pseudo-feature points to be a negative impact on fingerprint identification. While combining the traditional method has the advantage, for the spacing, direction offset small spacing, direction offset large fracture situation, this design window constraints window method and the improved two kinds of constraints, different repair methods. Experimental results show the method to fix a more comprehensive and complete removal of pseudo-feature points, easy to program, well thinned fingerprint image fracture repair.)
