摘要

Off-Grid wideband DOA estimation under low signal-to-noise ratio (SNR) and limited snapshots is a challenging problem for sonar array signal processing. In this paper, we proposed a novel joint sparse method with Generalized Orthogonal Matching Pursuit (J-GOMP). The method is on the basis of classical OMP with a double steering model parameters optimization. With the chosen of K terms in the largest absolute value of the inner product, the J-GOMP algorithm can achieve faster convergence speed. The detailed algorithm realization steps are given. Simulations are conducted in comparison with classical MUSIC and OMP algorithms. The results show the proposed J-GOMP has better resolution performance under low SNR with a single snapshot.
