One of the most striking challenges that radar designers have to deal with, when developing new doppler systems, is to overcome the difficulty of working with ambiguous velocities. Even using high PRF’s, target’s velocities become ambiguous because wavelengths are getting shorter. This article tries to depict an idea of becoming unambiguous in doppler, using only one PRF and without range tracking, taking advantage of target’s range migration if high range resolution radars are used. Simulations will be shown justifying the idea, but also, pointing out some limitations depending on the radar’s operational parameters and target’s relative motion.
