Abstract :
The authors propose an alternative wave equation-based time-space domain synthetic aperture radar (SAR) algorithm. The proposed algorithm can be interpreted as the exact time-space domain counterpart of the wave equation-based ω-k domain SAR algorithms proposed in recent years. Links to conventional SAR and seismic migration algorithm are also established
