摘要 该文针对机载双天线干涉SAR成像,分析了主、副两天线的波数域成像算法特点。通过在距离向引入距离平移因子和距离缩放因子,得到在成像过程中完成配准的波数域成像算法。通过计算机仿真和处理实际数据,验证了这种方法能够在机载双天线干涉SAR原始回波数据的成像处理中,完成复图像对的配准。 Aiming at airborne dual-antenna InSAR imaging, the characteristics of wavenumber domain imaging algorithms for master and slave antennas are analyzed. By introducing a range shift factor and a range scaling factor in range direction, a wavenumber domain imaging algorithm with completing registration during the course of imaging is presented. By means of computer simulation and processing practical InSAR data, the algorithm is demonstrated in completing registration between a pair of complex images during the course of processing original echoes data for airborne dual-antenna InSAR imaging.
