An Effective CS-BP Algorithm for 2-D DOA Estimation

摘要

The bandwidth of the direction of arrival (DOA) estimation requires high sampling rate which extends the current analog to digital converter capacity. The paper presents an effective basis pursuit (BP) algorithm based on compressive sensing (CS) signals, which is called CS-BP algorithm, for two-dimensional(2-D) DOA estimation of Linear Frequency Modulation (LFM). The simulation results verified that the method can effectively reduce the sampling data, and improve DOA estimation performance and efficiency.
