Abstract

Methods for processing an OFDM radar signal are provided. A plurality of Nc×NDS receive samples corresponding to a number of NDS consecutive OFDM symbols is received, each OFDM symbol comprising a plurality of Nc subcarriers modulated with a respective modulation symbol. Each of the plurality of Nc×NDS receive samples is divided by its respective modulation symbol to generate a number of NDS processed OFDM symbols. The number of NDS processed OFDM symbols is decimated to generate at least one decimated OFDM symbol. A first type discrete Fourier transform (e.g. IFFT) of the at least one decimated OFDM symbol is performed to generate at least one first transformed vector.
