| 摘 要： | 针对合成孔径雷达中由于多普勒中心偏移和谱宽扩展导致的"频谱分裂"问题,本文提出了一种基于"双门限"处理的频谱盲解分裂方法.基于单个距离单元的采样数据,新方法无需辅助信息便可实现正确的频谱解分裂.仿真性能分析和实际数据验证了新方法的有效性.

| Abstract: | Due to the width spread and center shifting of the Doppler spectrum,the "spectrum splitting" phenomena may be drawn in synthetic aperture radar.Based on a proposed double threshold processing,a novel method of blind spectrum splitting is developed.Via a single range unit sampling,the proposed method may correctly realize spectrum splitting without any other auxiliary information.Lastly,simulation experiments and real data are also provided to validate the proposed method. |

| Keywords: | synthetic aperture radar (SAR) spectrum splitting double threshold processing blind splitting solution |
