Imaging of fast moving targets using undersampled SAR raw-data
The paper proposes a novel methodology to estimate the velocity of fast moving targets using a single synthetic aperture radar sensor without increasing the Pulse Repetition Frequency. The basic reasoning is that, although the returned echoes may be aliased in the azimuth direction, its phase and amplitude are informative with respect to the moving target trajectory parameters. Based on this knowledge we built an estimator of the moving targets velocities and azimutal positions. These parameters allow focusing of fast moving targets on their correct azimuth positions.
