Abstract :
An ad hoc residual video phase (RVP) removal algorithm is developed for a spotlight SAR system employing dechirp-on-receive, and working with the polar format algorithm (PFA). In comparison with the existing RVP compensation approach, just two additional complex multipliers are required in the new algorithm to accomplish the range resampling of the polar formatting, in the meantime of RVP removal.
