Low-PAPR Waveforms with Shaped Spectrum for Enhanced Low Probability of Intercept Noise Radars [PDF]

open access: yesRemote Sensing, 2021
Noise radars employ random waveforms in their transmission as compared to traditional radars. Considered as enhanced Low Probability of Intercept (LPI) radars, they are resilient to interference and jamming and less vulnerable to adversarial exploitation
