Abstract :
Burst-mode data is obtained when a SAR system is operated in ScanSAR mode. First, a detailed description of the characteristics of the received burst-mode data is given. We then investigate the properties of the short IFFT (SIFFT) burst-mode processing algorithm and its input and output target space. A survey on the arithmetic of the SIFFT algorithm using the inverse momentary Fourier transform (IMFT) and the mixed-radix IFFT algorithms is given.
