We point out an issue with Lemma 8.6 of [1]. This lemma specifies the required sample complexity for recovering the delay-Doppler pairs in radar systems. In this lemma, it is claimed that the required sample complexity is linearly related to the number of delay-Doppler pairs. However, the way this result is proved seems to be wrong and leads to a quadratic relation. In this work, we provide a correction to the proof of this lemma.
