TCDA: Robust 2D-DOA Estimation for Defective L-Shaped Arrays
Wenlong Wang, Tianyang Zhang, Tailun Dong +1
While tensor-based methods excel at Direction-of-Arrival (DOA) estimation, their performance degrades severely with faulty or sparse arrays that violate the required manifold struc…

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 chirps from regularly spaced samples of their mixture is when . A ne…
