Analysis of spectral notching in FM noise radar using measured interference

It was recently shown that spectral notches can be incorporated into a physically realizable form of FM noise radar. Here it is shown how these spectral notches can be used to permit radar operation in a band where narrowband interference sources are present. The impact of interference and associated notches in different regions of the waveform spectrum (i.e. passband versus roll-off regions) is examined through assessment of the matched filter response when considering different receive power levels for the radar relative to measured interference. This assessment is performed for both simulated and experimentally measured notched waveforms.
