Abstract

The research community is constantly searching for a rich high range resolution (HRR) radar dataset against moving targets. Due to the lack of HRR sensors, however, these data are unavailable and progress in tracking and identification of moving targets has been slow. This effort represents an attempt to synthesize HRR profiles for ground moving targets from readily available stationary ground target measured and synthetic data. The measured data are taken from the extensive Moving and Stationary Target Acquisition and Recognition (MSTAR) program database. The synthetic data are generated using Xpatch scattering center models for ground targets. In both cases, the target data are segmented from any background clutter and then processed on a pulse-by-pulse basis to inject linear constant velocity motion onto the target. The results are displayed in a range/Doppler image. Targets exhibit range walk and Doppler smear as would be expected. A keystone technique is used to correct the linear distortions to the phase history and refocus the target HRR chips for sensors requiring longer HRR dwell times.
