OFDM radar has been studied in the last years for its suitability to combine communication and radar applications simultaneously. In this paper, we discuss the processing applicable to a train of OFDM pulses as from a radar prospective. We will focus on two different solutions. The first solution operates on the time domain signal while the second solution processes the signal in the frequency domain. We show that both solutions can be implemented by means of DFT and IDFT operations, which make them efficient in real time. We demonstrate that both achieve the same gain in SNR and we give examples based on simple scenarii.
