The main limitation for the practical implementation of OFDM radars is the required high sampling rate of AD/DA converters. It can be solved by using a stepped-carrier OFDM scheme. Thereby, the same range and Doppler resolution is obtained as for a standard OFDM scheme at the cost of a reduced unambiguously measurable velocity. This paper presents a method to determine the actual velocity even for targets that violate the unambiguous velocity limitation. It is based on characteristics of the
