Optimization of Angle-of-Arrival Estimation Via Real-Valued Sparse Representation With Circular Array Radar
Abstract
This paper suggests a real-valued sparse representation method using a unitary transformation that can convert complex-valued manifold matrices from uniform circular array into real ones. Because of this transformation, the computational complexity is modified. Simulation results confirmed the effectiveness of the proposed method with a circular array radar.
