Pursuing the limit of chirp parameter identifiability: A computational approach

Zai Yang, Sikai Ge, Wenlong Wang

In this paper, it is shown that a necessary condition for unique identifiability of $K$ chirps from $N$ regularly spaced samples of their mixture is $N \geq 2 K$ when $K \geq 2$ . A ne…
