Computationally efficient method for estimation of angle of arrival with non-uniform reconfigurable receiver arrays

The main focus of this paper is the design and formulation of a computationally efficient approach to the estimation of the angle of arrival with non-uniform reconfigurable receiver arrays. Subsequent to demodulation and matched filtering, the main signal processing task is a double-integration operation. The simplicity of this algorithm enables the implementation of the estimation procedure with simple operational amplifier (op-amp) circuits for real-time realization. This technique does not require uniform and structured array configurations, and is most effective for the estimation of angle of arrival with dynamically reconfigurable receiver arrays.
