Abstract :
This paper presents a SAR raw data simulation approach using the inverse frequency scaling algorithm (IFSA) based on deramp processing. It is time-saving and can take motion error into account. The limitation of the inverse chirp scaling algorithm (ICSA) on transmitted waveforms is also overcome. Simulated results show the validity of the algorithm.
