Ultra-wideband (UWB) nonlinear frequency modulation (NLFM) waveforms have the advantages of low sidelobes and high resolution. By extending the frequency domain wideband synthesis method to the NLFM waveform. the synthetic bandwidth will be limited. and the grating lobe will grow as the number of subpulses increases at a fixed synthetic bandwidth. https://www.lightemupsequences.com/mega-choice-Ball-of-Wisdom-on-sale/
