DOA Estimation Using Non-uniform Sparse Array with Unknown Mutual Coupling
2021 2nd Information Communication Technologies Conference (ICTC)(2021)
摘要
Due to the existence of dense subarray, nested array (NA) is susceptible to mutual coupling, which seriously degrades the parameter estimation performance. To deal with this problem, we propose an improved scheme to obtain direction of arrival (DOA) and mutual coupling estimation in this paper. Specifically, a new sparse subarray can be formed by moving specific sensors of the nested array, which ...
