2D Direction Finding as a Critical Technology in DOA Estimation

In signal processing, 2D direction finding technology plays a crucial role in Direction of Arrival (DOA) estimation. This technique typically involves array signal processing methods to determine the direction of signal sources. The program implements MATLAB simulations to calculate the angle of arrival, representing the signal source's directional angle relative to the sensor array. During simulation, users can adjust parameters and configurations to model various signal source environments and array setups, enabling more accurate results. The implementation may include algorithms like MUSIC (Multiple Signal Classification) or ESPRIT (Estimation of Signal Parameters via Rotational Invitation Techniques) for spectral estimation, with key functions such as array manifold calculation and covariance matrix processing. Further research on 2D direction finding technology enhances understanding of its underlying principles and applications, facilitating optimization and improvement across diverse practical scenarios through parameter tuning and algorithm refinement.
