Abstract
In this letter, we use the summation-by-parts formula as a simple tool to extend the estimation range of a certain class of the already existing correlation-based Doppler centroid estimators. The resulting estimators are as robust as the original ones but cover a much larger estimation range of about 50% of the pulse-repetition frequency. Two examples with simulations are provided to demonstrate the benefits of the proposal.
