DOA Estimation Algorithm for Dual-Target Narrowband Coherent Sources

Xinyi Wang

Open publisher page 2 citations

Abstract

Aiming at the feature of the narrowband signal received by linear array, an algorithm of the dual-target coherent sources DOA estimation is proposed in this paper. The algorithm can calculate the DOA of a single target or double targets directly by estimating space frequency of target signals. The principle of the algorithm is provided and simulated with programmed signal in this paper, and the factors of influencing DOA estimation are also analyzed in this paper. The simulation result shows that the algorithm has high estimation accuracy, regardless of signal length, the algorithm is convenient for real-time processing, and has a good application prospect.
