Comparison of OFDM radar and chirp sequence radar

The radar waveforms OFDM and chirp sequence are compared in terms of accuracy, resolution capabilities, receiver operating characteristics, required resources and signal processing. We show, that both waveforms can be parametrized in such a way, that they yield the same baseband signal which can be processed using the same detection and estimation algorithms. This key insight reveals, that in this case, the waveforms perform identical. However, OFDM additionally allows simultaneous communication using the radar signal at the cost of increased signal processing.
