DOA Estimation Under Amplitude and Phase Errors

Direction of Arrival (DOA) estimation under amplitude and phase errors presents a critical challenge in signal processing. When dealing with signal sources, accurately determining their direction of arrival requires robust estimation methods. I have developed a functional DOA estimation algorithm that provides precise localization of signal sources even in the presence of amplitude and phase distortions. The implementation utilizes array signal processing techniques with error compensation mechanisms, potentially incorporating calibration routines to mitigate amplitude and phase inconsistencies across array elements. This method employs advanced signal processing algorithms that can handle real-world imperfections, making it suitable for practical applications where accurate source localization is essential for better understanding signal source positions. The code structure likely includes matrix operations for covariance calculation, eigenvalue decomposition for subspace separation, and peak detection algorithms for angle estimation.
