MATLAB Simulation of 2D Angle Estimation Using Unitary-ESPRIT for Planar Arrays

This MATLAB simulation program implements 2D ODA (Orthogonal Dipole Array) angle estimation using planar arrays, effectively estimating spatial angles through the Unitary-ESPRIT algorithm. The algorithm represents a planar array-based 2D angle estimation technique that employs real-valued computations through unitary transformations, reducing computational complexity while maintaining estimation accuracy. The program utilizes predefined parameters to generate simulated signals and perform comprehensive testing, including array geometry configuration, signal subspace estimation via eigenvalue decomposition, and phase relationship extraction for azimuth and elevation angle calculation. This simulation assists researchers in understanding and applying 2D angle estimation algorithms for planar arrays, particularly demonstrating significant advantages when estimating higher-dimensional angles in spatial signal processing scenarios. The implementation includes key functions for signal generation, covariance matrix computation, and subspace rotation operations essential for accurate 2D parameter estimation.
