a fast strip-mode synthetic aperture radar raw data simulator of moving targets

a fast and accurate synthetic aperture radar raw data generator of moving targets has high importance, especially in the applications of ground moving target indication. in this paper, in the hybrid time-frequency domain, a fast algorithm for strip mode sar raw data generation of moving targets has been proposed. using this simulator, in different conditions in terms of target motion speed, acceleration and direction, radar raw data has been generated and its final image has been extracted by range-doppler algorithm. then, the obtained images has been studied using the formulae that has been extracted for prediction the effects of target motion parameters on the sar images. the results show that the proposed simulator has better performance in terms of accuracy and speed than the other existing simulators.
