Experimental Evaluation of Super-Gaussian-Shaped Random FM Waveforms

The class of noise radar waveform known as random frequency modulation (RFM) has been used to enable a variety of new sensing capabilities. It was also recently shown in simulation that a more compact design spectral template translates to better spectral containment, with a trade-off of emerging close-in “persistent” sidelobes. Here we take the next step of implementing in hardware sets of RFM waveforms designed in this manner to assess their loopback behavior and subsequently characterize their performance with open-air experimental measurements.
