Range‐ambiguity suppression for noise radar in cluttered environment via sparse recovery
Electronics Letters, 2021 Range ambiguity suppression is a significant problem in traditional pulse‐Doppler radar systems, especially when the pulse repetition frequency is set high to avoid Doppler ambiguity. One possible way to deal with such problem is to apply the noise radar
