中文摘要：
对于单通道SAR系统数据,已有成熟的检测快速运动目标的方法,但对于淹没在强主瓣杂波中的慢速运动目标检测尚待研究。针对这个问题,提出了一种有效的方法,来实现单通道SAR-GMTI对地面低速运动目标的检测。该方法通过对单通道SAR数据合理抽取和补偿,获得近似满足DPCA条件的两幅SAR复图像,然后进行复图像域DPCA处理。仿真和实测数据结果表明,该方法对强主瓣杂波中的地面慢速运动目标检测的有效性。并且在没有双通道SAR数据的情况下,采用本算法减少了系统成本和时间。
英文摘要：
There are sophisticated fast mobile targets detection algorithms for single-channel SAR data, while the algorithm for slow mobile target detection in strong main-lobe clutters remains to be developed. In view of this, this paper presents an effective method to realize the single-channel SAR-GMTI detection of slow mobile targets on the ground. The two complex SAR images satisfying DPCA condition can be obtained for the airborne single-channel SAR data by reasonable data extraction and compensation, and then complex image DPCA processing can be dealt with to clutter rejection. The simulation results and performance analysis show that the presented algorithm is effective for slow moving ground target detection, and its use can reduce system cost and save time without dual-channel SAR data.
