DOIAbstract
A software-based method for estimating and compensating for chirp non-linearity in frequency-modulated continuous wave radars is described. The method is based on the phase-gradient algorithm and time-domain warping of the dechirped signal. The method is demonstrated both on typically and severely non-linear chirps. The retrospective application is demonstrated on archive radar data.</p
