波数域算法在机载双天线干涉SAR成像中的应用

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.
