16365 之后，将方位历程图表示为低秩的混响、稀疏的运动目标回波和噪声成分，在此基础上提出以加速近端梯度法(APG)和快速数据投影法(FDPM)分别实现离线和在线的低秩稀疏分解，从而实现混响抑制和目标回波增强。 Accordingly, the bearing-time-record can be decomposed as low-rank reverberation, sparse moving target echo and noise components. To suppress reverberation and enhance target echoes, the Accelerated Proximal Gradient(APG) and Fast DataProjection Method(FDPM) are proposed to realize offline and online decomposition, respectively.
