Innovative Strategy for Stripmap SAR Imaging Using Fast Factorized Back-projection

  • 摘要: 快速分解后向投影(Fast Factorized Back-Projection, FFBP)最初用于超宽带SAR成像,并在聚束SAR信号处理领域取得了巨大的成功。然而,由于积分孔径和角域升采样的限制,FFBP算法难以直接用于条带SAR处理。为了提高FFBP算法在条带SAR处理的实用性,该文从积分孔径和角域波数带宽的角度出发,提出一种适用于条带SAR处理的重叠图像法。该方法极大地保留FFBP算法的运算效率,有效地避免因角域升采样带来数据量大的问题。最后,通过斜视条带SAR仿真实验验证了该方法的有效性。
