摘要：
A direction-of-arrival (DOA) estimation algorithm for non-circular signals with nested array is proposed. A closed formula is given to construct a partitioned fourth-order-cumulant (FOC) matrix by using the FOCs of received data. Then, an improved multiple signal classification (MUSIC) algorithm for non-circular signals (NC-MUSIC) based on FOC is introduced. The proposed algorithm shows higher estimation accuracy and angular resolution than some traditional NC-MUSIC algorithms, especially in the low SNR case. Some simulation experiments are proposed to prove the validity of the proposed algorithm. © 2019, Electromagnetics Academy. All rights reserved.
