Abstract

The frequency scaling algorithm (FSA) is proposed to process One-Stationary Spotlight Bistatic SAR (BiSAR) data acquired via the dechirp-on-receive approach. By using series reversion, we can derives the two-dimensional point target spectrum for this BiSAR configuration. This algorithm leads to a very precise and efficient processing since it performs the focusing in the frequency domain and no interpolation is required in the whole processing chain. This algorithm is verified with a point target simulation.
