Performances of multitones for ultra-wideband software-defined radar [PDF]
From the literature review, it is apparent that there is a gap in quantifying the performances of multitone waveforms specifically for radar applications and experimental results are not commonly found.

Research on LFM signal parameter estimation method based on Gabor transform to improve MWC system
The “compressed sensing” theory is the foundation for the compressed sampling system’s design. In addition to the sparse representation and observation matrix, more studies in compressed sensing theory focus on signal reconstruction and recovery.
