Abstract EN
This paper presents a novel two-dimensional (2D) direction of arrival (DOA) estimation method in compressed sensing (CS) to remove the estimation failure problem and achieve superior performance.
The proposed method separates the steering vector into two parts to construct two corresponding noise subspaces by introducing electric angles.
Then, electric angles are estimated based on the constructed noise subspaces.
In order to estimate the azimuth and elevation angles in terms of estimates of electric angles, arc-tangent operations are exploited.
The arc-tangent is a one-to-one function and allows the value of the argument to be larger than unity so that the proposed method never fails.
The proposed method can avoid pair matching to reduce the computational complexity and extend the number of snapshots to improve performance.
Simulation results show that the proposed method can avoid estimation failure occurrence and has superior performance as compared to existing methods.
