摘要：
In the aforementioned letter, the authors indicate that with a 2M + 1 sensor uniform linear array (ULA), up to 2M - 1 sources can actually be localized by the proposed algorithm. In this comment, however, we prove that the algorithm will no longer be valid if the number of sources exceeds. A numerical simulation is performed to verify this conclusion.
