All radar is dominated by high-bandwidth, fixed waveforms. All radar? No! A little domain combines communications and sensing, introducing OFDM Radar:

gr-ofdmradar is a GNU Radio out of tree (OOT) module, providing an OFDM Radar implementation that can be used in simulations and, potentially, hardware. In this talk I will introduce the motivations and theory behind OFDM Radar as described by Martin Braun, present gr-ofdmradar and how it can be used in simulations and conclude with a small outlook at how this module can be used for hardware implementations.
