Abstract
This paper discusses an implementation of bistatic polar format algorithm (PFA) using chirp scaling (CS). The new algorithm applies CS in the range direction to realize the range resampling, which involves only complex multiplications and FFTs. The dechirped and the chirped signals are treated separately. The new approach obtains comparable results compared with the original algorithm, however improves the efficiency significantly. Point target simulation validates the new algorithm.
