摘要：
The direction of arrival (DOA) estimation based on graph signal processing (GSP) has attracted a great deal of attention. Based on the results of the GSP approach to DOA estimation, the paper applies GSP to the coprime sensor array (CSA) for high precision estimating DOA of the narrowband signal. Simulation results show that the GSP-CSA performs well with lower root mean square error at low signal-to-noise ratio compared to classical DOA methods. The sea experimental data analysis has demonstrated the effectiveness of the GSP-CSA method with low computational cost.
