It was recently demonstrated that hopped spectral gaps can be incorporated into a physically realizable form of FM noise radar emission. Here it is shown using experimental loopback measurements how OFDM communications can be embedded into these spectral gaps and, by virtue of proper spectral shaping, realize a composite emission with low autocorrelation sidelobes. The impact of tandem hopping of the radar spectral gap and embedded communication signal is evaluated. An example of a spectrally shaped OFDM emission for use in a notional commensal radar setting is also presented.
