SAR pulse radio frequency interference suppression based on modified eigen subspace projection

本文提出了一种基于特征子空间投影的 SAR 射频干扰抑制方法。首先，检测含有 PRFI 的回波脉冲，分别通过时频域特征值分解和能量积累确定 PRFI 在脉冲中的具体位置。其次，通过将 ESP 方法仅应用于 PRFI 所在的数据，从有用信号中分离出 PRFI 信号。最后，从原始数据中剔除 ESP 投影的 PRFI 信号。仿真结果表明，该方法能够更好地保护有用信号，提高 SAR 图像质量。[pdf, EI]
