Experimental validation of sparse-frequency waveforms for congested spectrums

With more users populating the frequency spectrum and less available contiguous bandwidth, radar and communication waveforms are slowly forced to become more efficient at using their available frequencies. As waveform designs become more exotic, it is critical that future sparse-frequency methods also consider constraints imposed by amplifiers, such as modulus and phase restrictions. In this paper, three sparse-frequency waveform designs are compared. Experimental results are shown and validated against simulated data.
