摘要
合成孔径雷达(Synthetic Aperture Radar,SAR)是实现舰船目标监视应用的重要遥感手段之一。高分辨率宽测绘带(High Resolution Wide Swath,HRWS)SAR能够同时获取方位向高分辨率和宽测绘带SAR数据,为SAR图像舰船目标监视带来了新的机遇和挑战。该文综述了国内外SAR图像舰船目标监视技术研究现状,总结了舰船监视对SAR成像系统基本性能要求,结合HRWS SAR成像特点,分析了舰船目标监视面临的关键技术问题,重点介绍了研究小组在HRWS SAR图像舰船目标检测、特征提取、分类识别等关键问题的解决方案和初步研究成果,并指出需进一步研究的方向。
Synthetic Aperture Radar（SAR） is widely used in ship surveillance. High-Resolution Wide-Swath（HRWS） SAR data are simultaneously collected, which introduces challenges and offers new research opportunities.SAR-based ship-surveillance technologies and the performance requirements of SAR systems are reviewed and summarized. Furthermore, the characteristics of HRWS SAR imaging and ship surveillance technologies are considered in tandem, and preliminary research results on ship detection, feature extraction, and classification are discussed. Finally, we point out issues to be addressed in future work.
