Abstract
Synthetic aperture radar(SAR) is a radar system that can acquire high-resolution images of targets, regardless of weather and position of the sun. Some representative algorithms used for processing SAR signals and forming high-resolution SAR images from them are polar format algorithm(PFA), range migration algorithm(RMA), and back projection algorithm(BPA). This paper deals with the generation of simulated SAR signals of point targets and their subsequent processing using the PFA, which is a signal-processing algorithm that converts received signals in polar format to rectangular format. In addition, this paper provides an analysis of the performance and operation time of PFA through simulations and by applying parallel processing where each core is controlled by CPU affinity.
