Abstract
Methods for processing an OFDM radar signal are provided. A plurality of N×Nreceive samples corresponding to a number of Nconsecutive OFDM symbols is received, each OFDM symbol comprising a plurality of Nsubcarriers modulated with a respective modulation symbol. Each of the plurality of N×Nreceive samples is divided by its respective modulation symbol to generate a number of Nprocessed OFDM symbols. The number of Nprocessed 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.
